If the probability of an event is equal to 1, What must be true about the event?Group of answer choicesThe probability of the event happening and the probability of the event not happening are the same.The event is unlikely but not impossible.The event is impossible.The event is probable but not certain.The event is certain.

Given that the probability of an event is equal to 0.9, what must be true about the event? Group of answer choicesThe event is impossible.The event is very unlikely to happen.The event is certain to happen.The probability of the event happening and the probability of the event not happening are the same.The event is probable, but not sure to happen.

Probability is a measure of how likely an event is to occur. The probability of a certain event occurring is defined as the number of ways the certain event can occur or the number of favourable outcomes, divided by the total number of possible outcomes.If we flip a coin once, the probability of it landing on heads is 1/2. 1 being the favourable outcome (H) and 2 being all possible outcomes (H, T). We can write this out like so:P(1H) = ½When you flip a coin twice, the possible outcomes are: HH, HT, TH, and TT. If you flip a coin twice, what’s the probability of obtaining at least one head?
