Annie and her friends start a doubles club. the numbers below show information about all the members of the club. boys girls juniors 6 8 seniors 16 12 express the probability that annie chooses a girl or a junior. use the formula: p(aub)= p(a)+p(b)- p(anb)

Step-by-step explanation:

The given table :

                 Boys         Girls

Juniors       6               8

Seniors      16              12

Let G denote the event of choosing girl and J denote the event of choosing Junior.

Number of girls : 8+12=20

Number of Juniors : 6+8=14

Members that are girl and junior = 8

Total students : 6+8+16+12=42

The probability of choosing girl is given by :-

The probability of choosing junior is given by :-

The probability of choosing a girl and junior is given by ;-

Now, the probability choosing a girl or a junior is given by :-

Hence, the  probability that Annie chooses a girl or a junior=

180
