1/4
It is 1/2.
Sample space for two coins tossed is: HH HT TH TT Therefore at most one head is HT TH TT or 3/4 or 0.75.
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
There are 36.

The sample space consists of the following four outcomes: TT, TH, HT, HH
1 in 4
1/4
The odds are 1 in 2.
Flipping a coin: two possible outcomes, H or T. Rolling a die: six possible outcomes, 1, 2, 3, 4, 5, or 6. Flipping a coin and rolling a die: 12 possible outcomes. So the sample space has 12 outcomes such as, {H1, H2, H3, H4, H5, H6, T1, T2, T3, T4, T5, T6 }
It is 1/2.
1/2
Sample space for two coins tossed is: HH HT TH TT Therefore at most one head is HT TH TT or 3/4 or 0.75.
There are 8 permutations of flipping a coin 3 times, or of flipping 3 coins one time. They are, with the permutations of two heads bolded...TTTTTHTHTTHHHTTHTHHHTHHH... thus, the probability of flipping a coin 3 times and getting 2 heads is 3 in 8, or 0.375.
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
There are 36.
