Do you think the sum of the probabilities for all outcomes of any experiment will always be one?
do you think that the sum of the probabilities for all outcomes of some experiments can be greater than one?

explain your reasoning,

The probability of an event is a measure of the likelihood that the event will occur. By convention, statisticians have agreed on the following rules.

The probability of any event can range from 0 to 1. The probability of event A is the sum of the probabilities of all the sample points in event A. The probability of event A is denoted by P(A).

Thus, if event A were very unlikely to occur, then P(A) would be close to 0. And if event A were very likely to occur, then P(A) would be close to 1.

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
