Tristan Hebert · Answer 1

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.
