The probability of drawing a Queen of Hearts from a standard deck is 1 in 52, or about 0.01923. The probability of drawing a blue card from a standard deck is zero, because there are no blue cards. Simply add them together 0.01923 + 0 = 0.01923.
The probability of randomly choosing 1 blue sock is 7/10. The probability of randomly choosing 2 blue socks in a row is 7/10 x 7/10 = 49/100.
It can not be determined with the data provided.
it depends how many blue marbles there are and how many marbles total.
if there is a jar containing 5 red marbles 6green and 4 blue what is the probability off not chossing a blue marble
The probability of choosing a blue marble is 5 in 15 or 1 in 3. The probability of then choosing a green marble is 5 in 14. (One is missing) Multiply the two probabilities and you get 5 in 42.(P = 0.1190... about 12%).
100%
This is the same as the probability of choosing either a red of a blue marble. There are 5+4 out of 15 ways of doing this. The probability is therefore 9/15 = 3/5.
cant answer this question without more information....probability requires a ratio.

The answer depends on how many blue and non-blue marbles there are, whether the choice is random and how many marbles are chosen. There is no information provided on any of these.
