What is the probability that a student randomly selected from a class of 60 students will be a male who has brown hair?

vovikov84 [41]

Answer:

1/6 ( under not enough of other criteria)

Step-by-step explanation:

total of student: 60

1/3 male: 60 x 1/3 = 20

Female = 60 - 20 = 40

1/2 with brown hair: 60 x 1/2 = 30

It seems the answer of 20/60 x 30/60 = 1/3 x 1/2 = 1/6 is the result, but consider the brown hair number is larger than male student (30 vs 20). Therefore there can have the chance of all the boys are brown hair and be chosen, then the probability will become 20/60 = 1/3. While probability result is not a certain result, it only to predict how likely things are to happen.

Therefore I think 1/6 is an answer.

A gambler in Las Vegas is cutting a deck of cards for $1,000. What is the probability that the card for the gambler will be the

White raven [17]

Answer:

a. 3/13 or 23.08%

b. 1/13 or 7.69%

c. 1/4 or 25.00%

d. 1/52 or 1.92%

Step-by-step explanation:

Number of cards in a deck = 52

a. A face card

Considering there are four suits and each suit has three different face cards, the probability that the card is a cafe card is:

$P_{F} =\frac{3*4}{52}\\ P_{F} =\frac{3}{13}$

b. A queen

There are 4 queens in the deck, on of each suit, thus the probability of getting a queen is:

$P_{Q} =\frac{4}{52}\\ P_{Q} =\frac{1}{13}$

c. A spade

There are four suits with the same number of cards in a deck, therefore, the probability of getting a spade is:

$P_{S} =\frac{1}{4}$

d. A jack of spades

Since there are no repeated cards, there is only one jack of spades in a 52 cards deck:

$P_{J+S} =\frac{1}{52}$
