Question 910208: Let X be the number from 5 randomly selected teenagers who have sent text messages on their phone in the past month. The probability distribution is as follows:
x P(x)
0 0.015
1 0.097
2 0.258
3 0.343
4 0.227
5 0.060
Find the probability that three or more of the teenagers sent text messages.
Find the probability that fewer than two of the teenagers sent text messages.

Find the probability, P(2)
Find the probability, P(X>1)
