Pr(Red queen) = 2/52 = 1/26 = 3.85%
Pr(4 on a die) = 1/6 = 16.67%
Pr(Red queen AND 4 on a die) = 1/26 * 1/6 = 1/156 = 0.64%

2/5
An event can either happen or not happen. If the probability of it happening is 3/5,then the probability of it not happening is 2/5.
There are two black 7's and two red queen's in a standard deck of playing cards. The probability of drawing a black 7 is 2 in 52, or 1 in 26, or about 0.038. The probability of drawing a red queen from the remaining 51 cards is 2 in 51, or about 0.039. The probability, then, or drawing a black 7 followed by a red queen is (2 in 52) times (2 in 51), which is 4 in 2652, or 2 in 1326, or about 0.00151.
The probability of drawing a red queen in a complete package of playing cards (ignoring jokers) is 1/26 or approximately 3.8%. There are 26 red cards in a deck of 52 cards. There are 2 red queens in those 26 red cards (one queen of diamonds and one queen of hearts). SO: 2 / 52 = 1 / 26 = approximately 3.8%.
The probability of drawing two red cards with replacement is (1 in 2)2 or (1 in 4) or 0.25
