SOLUTION: what is the probability of rolling a 3 with a dice, and drawing a 3 from a deck of cards? I know both events are independent and P(A and B) + P(A) x P(B) formula should be used.

Question 1156968: what is the probability of rolling a 3 with a dice, and drawing a 3 from a deck of cards?
I know both events are independent and P(A and B) + P(A) x P(B) formula should be used.

P(A) = probability of getting 3 on a throw of dice
P(A) = 1/6
P(B) = probability of getting a 3 from a pack of card
P(B) = 4/52 ( since there are 4 3s in pack of 52 cards)
Probability of both the events happening together
= P(A) × P (B)
= 1%2F6+%2A+4%2F52
= 1%2F78
