This may be wrong but it sounds to be about 7.7% because when you find probability is the total number of favorable cases (in this case jacks) divided by the total number of cases (52 cards) therefore wouldnt it be 4/52 which is 0.0769230769 which you multiply by a hundred to get a percentage?

The most appropriate choice for Probability of an event will be given by-

P(7) = \frac{1}{3}

What is Probability?

Probability gives us the information about how likely an event is going to occur

Probability is calculated by Number of favourable outcomes divided by the total number of outcomes.

Probability of any event is greater than or equal to zero and less than or equal to 1.

Probability of sure event is 1 and probability of unsure event is 0.

Here,

Sample space = {6, 7, 8}

Total number of outcomes = 3

Favourable outcomes = {7}

Number of favourable outcomes = 1

Probability of getting a 7 = P(7) = \frac{1}{3}
