20% of skittles candies in a bag are red. If you randomly pull 4 skittles out of the bag, what is the probability at least one of them is red

Answer:

0.5904

59.04%

Step-by-step explanation:

1/5 red

4/5 other

Probability of A occuring 4 time(s) = 0.24 = 0.0016

Probability of A NOT occuring = (1 - 0.2)4 = 0.4096

Probability of A occuring = 1 - (1 - 0.2)4 = 0.5904
