Coin 1 H T or T H Coin 2 H T or T H 4 Combining H T T H H T T H From this table the result can be 2 x H 2 x T H T or T H
The sample space for tossing 2 coins is (H = Heads & T = Tails): HH, HT, TH, TT
The sample space is 23 or 8; which can be listed out as: HHH, HHT, HTH, HTT, THH, THT, TTH, TTT. There are 2 of the 8 that have exactly 2 heads; so the probability of exactly two coins landing on heads is 2/8 or 1/4.

There are 4 events: 3 heads, 2 heads 1 tail, 1 head 2 tails, and 3 tails.

The probability of tossing two heads in two coins is 0.25.
The probability that the die tossed will land on a number that is smaller than 5 is 4/6 or 2/3. Smaller than 5 is 1 - 4 and 6 is the sample space.
There are 2^n elements, where n is the number of coins.
2*2*2*2 = 16
