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.
