One card is drawn from a standard 52-card deck. Determine the probability that the card is a) a spade, b) a spade, given that the card is a black card. . . . . . a) The probability that the card is a spade is (Type an integer or a simplified fraction.) b) The probability that the card is a spade, given that the card is a black card, is (Type an integer or a simplified fraction.)Consider the tennis balls shown in the accompanying figure. Assume that one tennis ball is randomly selected. a) Determine the probability that the ball selected shows an even number. green orange yellow yellow orange green b) Determine the probability that the ball selected shows an even number, given that the ball is green. If pointer 1 is spun and then pointer 2 is spun, determine the probability of landing on a color other than green on both spins. Pointer 1 + Pointer 2 R R R . . . . . The probability is. (Type an integer or a simplified fraction.)
