Two cards are drawn without replacement from a deck of 52 cards.
a. What is the probability of drawning 2 aces?
b. What are the odds in favour of drawing 2 honour cards? (A, K, Q, J, 10)
Please type your subject in the School Subject box. Any other words are likely to delay responses from a teacher who knows that subject well.
The probability of drawing the first ace is 4/52. Without replacement, the probability of drawing the second ace is 3/51. (Do you understand why?) The probability of events all happening is found by multiplying the individual probabilities.
The probability of drawing the first "honour card" is 20/52. Use the same methodology as in the above problem.
I hope this helps.
