In a class there are 10 students who play football and cricket
7 who do not play football or cricket
14 students who play football
21 students who play cricket
find the probability that a student chosen at random plays football and cricket.

The probability that a student chosen at random plays football and cricket is 0.3125 or 31.25 %

Solution:

Given that,

In a class there are 10 students who play football and cricket

14 students who play football

21 students who play cricket

7 who do not play football or cricket

The venn diagram is attached below

From venn diagram attached below,

Find the total number of students

Total = 4 + 10 + 11 + 7 = 32

Thus total number of students are 32

Find the probability that a student chosen at random plays football and cricket:

From venn diagram,

See the intersection of football and cricket

10 play football and cricket

The probability is given as:

Therefore,

Thus the probability that a student chosen at random plays football and cricket is 0.3125 or 31.25 %

homozygous. one is homozygous, while two is heterozygous.

step-by-step explanation:

ok one would be money, and the other would be refreshments or something similar. if each bag of popcorn is 5.00 and each drink is half of that that means drinks are 2.50 the proper way to do that would to look and see how much of each you can buy without exceeding a limit of 30.00
