Ted is not particularly creative. He uses the pickup line"If I could rearrange thealphabet, I'd put U and Itogether." The random variable x is the number of girls Ted approaches before encountering one who reacts positively. Determine whether the table describes a probability distribution. If itdoes, find its mean and standard deviation.

1 0.001

2 0.035

3 0.132

4 0.283

5 0.164
