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.

a , b,  d

Step-by-step 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.
