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?

2/5

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
