The probability that you pick a blue then red beach ball is 1/4 if there are five blue beach balls and five red beach balls in a bin option (A) 1/4 is correct.
It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
It is given that:
There are five blue beach balls and five red beach balls in a bin.
You pick a beach ball at random and then put it back in the bin.
Then you pick a second beach ball at random.
Total number of outcomes = 10x10 = 100
Number of favourable outcomes = 5x5 = 25
A probability that you pick a blue then red beach ball:
P = 25/100
P = 1/4
Thus, the probability that you pick a blue then red beach ball is 1/4 if there are five blue beach balls and five red beach balls in a bin option (A) 1/4 is correct.
