Question

Check all the statements that are TRUE:

a. A probability of 1/10 indicates an unusual event.

b. When an event is almost certain to happen, its complement will be an unusual event.

c. You toss a coin and roll a die. The event "tossing tails and rolling a 1 or a 3" is a simple event

d. You toss a fair coin nine times and it lands tails up each time.

e. The probability it will land heads up on the tenth toss is greater than 0.5.

Answer 1

a , b, d

Explanation:

The probability of 1/10 is simply an unusual occurrence , while the complement or opposite of a certain event is an unusual event. Tossing a coin and rolling a die together is a compound event. A fair coin when tossed can land tails every other time but that does not change the probability for head or tail which is always 0.5.
