If only one person is picked at random then the probability is 1/16 = 0.0625
The probability of NOT getting heads is (1/2)4=1/16 Therefore the probability of getting heads is 1-1/16=15/16
4/7 * 4/7 or 16/49.
As the question is "what is the probability of getting at least one head" the correct way to answer this is to ask what is the probability of not getting any heads and then subtract this from 1.The probability of not getting a head in 4 flips = 0.54 (i.e. 0.5 * 0.5 * 0.5 * 0.5) = 1/16.Therefore the probability of getting at least one head is 1 - 1/16 = 15/16.
2/16 = 1/8 or 12.5
Assuming a 6 sided die, a roll of 2 gives a maximum value of 12. So the probability of getting a 16 is zero.
The probability of getting all heads is 1/24 = 1/16 The probability of getting all tails is also 1/24 = 1/16 The probability of all heads or all tails is the sum of the two = 1/8
1 out of 16
There are 4 tens and 13 spades but one of these is the ten of spades. So there are 4 + 13 - 1 = 16 cards which lead to "success". Therefore the probability is 16/52 = 4/13
If you look at the as the probability of getting 1 or more tail in 4 coin tosses, you would then calculate the probability of tossing 4 heads in a row and subracting that from 1. The probability fo tossing 4 heads is 1/2 * 1/2 * 1/2 * 1/2 = 1/16. 1 - 1/16 = 15/16.
Assuming it is a fair coin, the probability is 1/24 = 1/16.
It is 1/16.
0.54 or 0.0625 or 1/16.
