Question 181533
number of ways red can occur 5
total of possible outcomes is 20
:
so to choose 1 red P(r)= 5/20
then you lose one red ball so our number of ways red can occure is now 4 and the total possible outcomes is 19. hence:
:
P(r)=4/19
:
for the probability of this you multiply these together
:
(5/20)(4/19)=(20/20*19)=1/19
