Ted is not particularly creative. he uses the pickup line "if i could rearrange the alphabet, i'd put u and i together." 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 it does, find its mean and standard deviation. if a probability distribution is not given, identify the requirements that are not satisfied.
x p(x)
1 0.001
2 0.025
3 0.101
4 0.246
5 0.503

Not a probability distribution

Step-by-step explanation:

The given table doesn't describe a probability distribution as in order for the given distribution to be a probability distribution the sum of probabilities is required to be equal to one.

Here,

Sum of probabilities = 0.001+0.025+0.101+0.246+0.503 = 0.876

The sum of probabilities is not equal to one.

Therefore, the given distribution is not a probability distribution ..

answer: median

step-by-step explanation:

the median is the middle value when a data set is ordered from least to greatest

24

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24
