Question

If you think the probability of getting A on an exam is 10%, while the probability of getting B on the exam is 30%, what is the probability of getting A or B on the exam?

Answer 1

2/5

Step-by-step explanation:

Probability of "A" is 10% = 1/10

Probability of "B" is 30% = 3/10

The probability of A of B = P(A) + P(B)

= (1/10) + (3/10)

= 4/10

= 2/10
