Answer:

D. The probability of the pointer landing on yellow is equal to the probability of the pointer landing on red.

Step-by-step explanation:

The spinner is divided equally in 4 parts, which are Red, Yellow, Green and Blue. This means that every part of the spinner equals 25%, because 100 / 4 is 25. With that in mind, the probability of the pointer landing on one of the parts are the same to all of them; 25%.

Answer:

The probability that Swallows will win the trophy is 0.8064

The probability that Rucks will win the trophy is 0.1936

Step-by-step explanation:

For each game, there are only two possible outcomes. Either the Swallows win, or they do not. The probability of them winning a game is independent of any other game, which means that the binomial probability distribution is used.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$
