Problema Solution
the red face cards and the black face cards number 2-9 are put in a bag. two cards are drawn without replacement. find the probability both are red
Answer provided by our tutors
There are 8*2 = 16 red-faced cards and 8*2 = 16 black.
First Card red = 16/32
Second card red = 15/31
The probability of all occurring is found by multiplying the individual probabilities
p = (16/32)*(15/31)
p = 0.242
the probability that both will be red is 0.242.
