Explain why the two sets are equivalent.
a={the letters in the word seat}
b={the letters in the word taste}
a. the two sets are not equivalent because set a has 4 letters and set b has 5.
b. both sets contain the same elements.
c. both sets contain objects.
d. both sets contain letters.

B. Both sets contain the same elements.

Step-by-step explanation:

Given:

A={The letters in the word SEAT}  

B={The letters in the word TASTE}

Writing the sets in elements form

A = {S,E,A,T}

B={A,S,T,E} => the letter T appears two times but the repeating elements are written only once.

Hence, both sets contain the same letters.

Therefore, the correct answer is:

B. Both sets contain the same elements ..

answer: t=3

step-by-step explanation:

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0
