Answer:

a) 1/4

b) 3/4

Possible outcomes of two tosses of a coin:

There is a total of 4 possible outcomes.

p(event) = (number of desired outcomes)/(total number of possible outcomes)

a) 2 heads

HH <------- 1 desired outcome

p(2 heads) = 1/4

b) at least 1 head

HH \

HT } <------ 3 desired outcomes
