Final answer:
The correct answer to the probability of Jacob choosing either a four or a six from a standard deck of 52 cards is option a) 1/13, which is found by adding the probability of drawing a four and a six together.
Step-by-step explanation:
The student has asked about the probability of choosing either a four or a six from a standard deck of 52 cards. In a standard deck of cards, there are four fours and four sixes, one of each in every suit (hearts, clubs, diamonds, spades). To find the probability of drawing either a four or a six, add up the probabilities of drawing each:
Probability of drawing a four: 4 out of 52 cardsProbability of drawing a six: 4 out of 52 cards
To combine these, remember that the events are mutually exclusive (you can't draw a four and a six at the same time), so you simply add the probabilities:
Probability of drawing either: (4/52) + (4/52) = 8/52 which simplifies to 1/13, therefore the correct answer is option a) 1/13.
