00:00Hi kids! Today we will learn what is probability. So let's get started!
00:10Here is an empty box and I put five red balls in it and two blue balls in it.
00:23Now, if I pick out any one ball from the box without looking, which ball am I most likely to pick out?
00:37Red balls because red balls are more in number than blue balls. So picking up red balls
00:49is more probable or most chances are there that red ball will come out
00:58if we take out one ball from the box. Good! Now, let's take another example.
01:09Here is a box and I add one black ball in it, four red balls in it, and nine yellow balls.
01:25Now, if I pick out any one ball from the box without looking into the box,
01:34which ball am I least likely to pick? Think! Least likely? Black ball because there is only
01:47one black ball in the box. So it is least probable that black ball will come out. Good!
01:57Now, if I pick out any one ball from the box without looking into the box,
02:08which ball am I most likely to pick? Most likely? Yellow ball because most number of balls in the
02:20box are yellow. So it's most likely that if I pick one ball from the box, it will be yellow ball
02:31or it is most probable that yellow ball will come out. Good! So here we are finding out
02:44the probability of happening or not happening something. Now,
02:51you know what's the meaning of probability.
02:57Which word is best suitable to describe the chance of spinner landing at one?
03:04Likely, maybe, or never? The answer is maybe because one is written only once on the wheel.
03:20So it's least likely or maybe that spinner will land on one. Good!
03:29Now, which word is best suitable to describe the chance of spinner landing at three?
03:40Likely, unlikely, maybe, or never? The answer is likely because three is written maximum number
03:55of times on the spinner wheel. So it's most likely that spinner will land on three. Good!
04:07Now, which word is best suitable to describe the chance of spinner landing at two?
04:15Likely, unlikely, or never? The answer is unlikely because two is written only two times,
04:33which is less than the number written most number of times. So it's unlikely that spinner will land
04:43on two. Good! Now, which word is best suitable to describe the chance of spinner landing at five?
04:57Likely, unlikely, or never? The answer is never because five is not written on the wheel.
05:11So it's not possible at all that spinner will land at five. Good! Now you have a fair idea
05:21what is probability. It is a chance of happening or not happening something.
05:29Now you may go ahead and take a quiz to learn more. Bye-bye!
