In a pile of cards, there are four hearts, twelve clubs, and eight diamonds. How many times would we expect a diamond to be drawn in 300 trials?

a. 150

b. 100

c. 75

d. 50

The correct answer is c. 100.

Step-by-step explanation:

Number of cards in the given pile = 24

Total number of diamond cards in the pile = 8

Probability of picking up a diamond in a draw of card from the pile is given by .

There are supposed to be 300 trials.

Therefore number of times a diamond card is picked from the pile is given by 300 × = 100.

Out of 300 trials to pick a card, about 100 times we can expect to have picked up a diamond card from the pile.

step-by-step explanation:

ez

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
