1. Anna was invited to prom by two different dates, Tyler and Max. She doesn't want to hurt anyone's feelings, so decides to mak

e a fair decision between the two. She rolls 2 dice and selects a prom date based on their sum. If the sum is 2, she'll go with Tyler. If the sum is 12, she'll go with Max. If the sum isn't 2 or 12, then Anna ignores it and rolls again. Is this a fair decision?
A. The decision isn't fair because Tyler has a better chance of being selected.
B. The decision isn't fair because the method of selection isn't random.
C. The decision is fair because both Tyler and Max have equal chance of being selected.
D. The decision isn't fair because Max has a better chance of being selected.

Answer:

C. The decision is fair because both Tyler and Max have equal chance of being selected.

Step-by-step explanation:

Hi there! I'm glad I was able to help you!

Since the probability numbers that were rolled by Anna aren't given to us, neither choice A, B, or D are correct. Neither Tyler nor Max have a higher chance of being selected over one another.

Answer choice C would be your best bet, considering no numbers were mentioned. Anna only wants to land on either 2 or 12, in this case she landed on neither.

I hope this helped you! :)

Simon must maintain an average grade of 80% or better in his math class to be eligible to play sports.His math grade so far are
Sophie [7]

Answer:

Let x be the percentage score he got in fifth test,

According to the question,

His score in first, second, third and fourth test are 80%, 84%, 76% and 77% respectively,

Thus, the average of his total score in the five test,

= \frac{80+84+76+77+x}{5}

But, Again according to the question,

The average of the five grades as greater than or equal to 80%

That is,

\frac{80+84+76+77+x}{5}\geq 80

⇒ \frac{317+x}{5}\geq 80

⇒ 317 + x \geq 400

⇒ x\geq 83

Thus, the least score he can get in the fifth test is 83.
