The probability of an event can only be between 0 and 1 and can also be written as a percentage. The probability of event A ‍ is often written as P (A) ‍ . If P (A) > P (B) ‍ , then event A ‍ has a higher chance of occurring than event B ‍ . If P (A) = P (B) ‍ , then events A ‍ and B ‍ are equally likely to occur.To determine the p-value, we will compare the test statistic (χ2) to the chi-square distribution with (n−1) degrees of freedom. Since the alternative hypothesis (H A) is σ2 >50, it's a right-tailed test. Given: χ2 = 27.075. Degrees of freedom: df =n−1= 16−1 = 15. Using the chi-square distribution, we can find the p-value for the given ...a) A die is rolled, find the probability that the number obtained is greater than 4. b) Two coins are tossed, find the probability that one head only is obtained. c) Two dice are rolled, find the probability that the sum is equal to 5. d) A card is drawn at random from a deck of cards.
