Seven musicians (R, S, T, U, V, W, X) are playing in Lalapolza, Poland for a charity. What is the probability of ordering these acts if: T is first. The order is U, V, X, W, T, S, R. R is fifth and W is last. T or V are third. a. What is the probability of T being first.
b. What is the probability of the order being exactly U, V, X, W, T, S, R?
c. What is the probability of R being fifth and W is last?
d. What is the probability that T or V are third?

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!

its line 2 i just added the rest or else it wouldn't let me answer
