Consider the random variable x whose probability distribution is given below:

x | pr(x=x)

1 | 0.5

3 | 0.35

5 | 0.1

7 | 0.05

what is the probability that x is at most 6.7? what is the probability that x is at least 6.7?

hope it

step-by-step explanation:

x^(1/6) · x^(1/6) · x^(1/6)   ·x^(1/6) = x^(4/6)   since we add the exponents

4/6 can be simplified to 2/3

the simplified form is x^(2/3)

in if you ask questions, the points are taken from your total and given to the one who answered it..

so if i have 30 points and i ask a question for 5 points, then when someone asks a question i will lose 5 points and the answerer earns 5
