Suppose a bag contains 4 white chips and 6 black chips. what is the probability of randomly choosing a white chip, not replacing it, and then randomly choosing another white chip?

There are 4+6=10 chips in the bag. 4 of them are white. The probability that the first chip chosen will be white is 4/10=2/5.
After that, there is one white chip less in the bag, so there are 9 chips in the bag, 3 of them are white. The probability that the second chip chosen will be white is 3/9=1/3.

Multiply the probabilities to find the probability that the first chip will be white and the second chip will be white:


The probability of choosing a white chip and then another white chip is 2/15.

--The probability of choosing a white chip on the first draw is 4/10 .

-- If you already have one white chip, then the probability of choosing
another one on the second draw is 3/9.

--  So the probability of both is  (4/10) x (3/9) = 12/90 = (13 and 1/3) percent .

Deja qué x = longitud6(x) = 48cm^2divide por 6: x = 8la área de longitud es 8 cm.

i think there was a typo. you wrote pat brings 3 quarts of ice-cream to the party. each serving of ice-cream is 1 6 quart. how many total servings of ice-cream does pat bring to the party? i think the bold is supposed to be 1/6. so 1 quart of ice cream = 6 servings. 6 * 3 = 18.

the answer is 18.
