there are 8 cards, five are black and three are white.The question is " Find the probability of icking a black than white card. HELP PLEASE!!!!
It would help if you proofread your questions before you posted them. Do you mean "then"? Also, do you mean without replacing the black card? I will assume so.
Black card = 5/8
White card = 3/7
The probability of all/both events occurring is found by multiplying the probabilities of the individual events.
To find the probability of picking a black card and then a white card, you need to calculate the probability of each event happening separately and then multiply the probabilities together.
Let's break down the problem:
First, we calculate the probability of picking a black card from the 8 cards. There are 5 black cards out of 8 total cards, so the probability of picking a black card is 5/8.
Second, we calculate the probability of picking a white card from the remaining cards after picking a black card. After removing one black card from the deck, there are 7 cards left, of which 3 are white. So the probability of picking a white card is 3/7.
Now, to find the probability of both events happening, we multiply the two probabilities together:
(5/8) * (3/7) = 15/56.
Therefore, the probability of picking a black card and then a white card from the given deck is 15/56, or approximately 0.268.
Remember that to get the probability of a series of events happening, you multiply the probabilities of each event together.
