Answer:
4/13
Explanation:
The question asking to find P(jack or heart)
You have to use the formula below:
P(A or B) = P(A) + P(B) - P(A and B)
Event A here is jack and event B is heart, now let's find the three probabilities on the right side to be able to find the left side.
P(jack) =4/52 because there are 4 jacks in a standard deck of cards
P(heart) =13/52 because there are 13 heart cards
P(jack and heart) =1/52 because there is only one jack card with a heart symbol
Now, plug in the three answers in the above formula:
P(jack or heart) = 4/52 + 13/52 - 1/52
this equal to 16/52
Last step, reduce the result by dividing the top and the bottom numbers by 4
The final answer is 4/13
