Question

i feel absolutely unintelligent and cannot get past this assignment. all my friends finished school but im not done yet. can someone help me please!

Answer 1

Explanation:

Probability of A is 10 + 5 =15

Probability of B is 9 + 5 ( but you already counted the '5')

so just count 9

9+ 15 = 24

this is 24 out of 16 + 10 + 5 + 9 = 40

or 24/40 which reduces to 3/5 or .6 or 60%

Using the equation given:

P(A) + P(B) - P(A and B)

15 + 14 - 5 = 24 this is out of the entire number 40

24/40 = same as above
