Back

Impossible, as a 6-sided die only has numbers 1 through 6.

Front

What is the probability of rolling a 6 on the first roll and an even number on the second roll with a standard die?

Back

1/12

Front

How do you calculate the probability of drawing a black sock followed by a yellow sock without replacement from a drawer containing 2 white, 6 black, and 4 yellow socks?

Back

The probability is (6/12) * (4/11) = 2/11.

Front

What is the probability of choosing a letter other than 'A' from the word 'ALGEBRA'?

What is the probability of drawing two specific colored socks from a drawer containing multiple colors?

Back

Calculate by multiplying the probability of drawing the first color by the probability of drawing the second color after the first has been removed.
