Having problems with probabilities

Question

The accompanying table describes results from eight offspring peas. The random variable x represents the number of offspring peas with green pods. 

 

Probabilities of Number of Peas with Green Pea Pods Among 8 Offspring Peas

(Number of Peas w/Green Pods) 

 

x      P(x)
0        0+
1        0+
2        0.001
3        0.018
4        0.085
5        0.199
6        0.286
7        0.303
8        0.108
Find the probability of getting exactly 7 peas with green pods.

Answer 1

P(x) represents the probability of getting x peas.  Thus to get the probability of 7 peas you would simply look up the value of P(x) for x=7 in the table.
