What happens if I don’t do well on the accuplacer test? I suck at math.

If I score low on math will they give me a remedial/low level math course?

That depends upon the college. Ask a counselor at that college.

The table shows the results of spinning a four-colored spinner 50 times. Find the experimental probability and express it as a decimal.

P(not red) = ?

Color | red | blue | green | yellow
# of | 20 | 10. | 9 | 11
Times
Spun

A. 0.6
B. 0.4
C. 0.2
D. 0.3

P(not red) = P(blue) + P(green) + P(yellow)

P(not red) = (10 + 9 + 11) / 50

P(not red) = 30 / 50

P(not red) = 0.6

Therefore, the answer is A. 0.6.

You roll a number cube 20 times. The number 4 is rolled 8 times. What is the experimental probability of rolling a 4?

A. 40%
B. 25%
C. 20%
D. 17%

Experimental probability of an event happening is equal to:

(number of times the event occurs) / (total number of trials)

In this case, the event is rolling a 4 and the total number of trials is 20.

Experimental probability of rolling a 4 = 8/20 = 0.4

Converting 0.4 to a percentage: 0.4 x 100 = 40%

Therefore, the answer is A. 40%.

The table below shows the results of flipping two coins. How does the experimental probability of getting at least one tails compare to the theoretical probability of getting at least one tails

Outcome | HH | HT | TH | TT |
Numbers | 28 | 22 | 34 | 16
Of times
Tossed

A. The experimental probability is 3% greater than the theoretical probability.
B. The theoretical probability is 3% greater than the experimental probability.
C. The experimental probability is equal to the theoretical probability.
D. The experimental probability is about 1% less than the theoretical probability.

The theoretical probability of getting at least one tails on flipping two coins can be found using the probability of the complement event, i.e. getting no tails on two flips:

P(no tails) = P(both heads) = 1/4

P(at least one tails) = 1 - P(no tails) = 1 - 1/4 = 3/4

The experimental probability of getting at least one tails can be found by adding up the frequencies of getting at least one tails:

Experimental probability of getting at least one tails = (22 + 34 + 16) / 100 = 0.72

Comparing the experimental and theoretical probabilities, we get:

Difference = |Experimental probability - Theoretical probability| * 100 %

Difference = |0.72 - 0.75| * 100 % = 3%

Therefore, the answer is A. The experimental probability is 3% greater than the theoretical probability.

The probability of winning a game is 15%. If you play 20 times, how many times should you expect to win?

A. 5 times
B. 3 times
C. 6 times
D. 15 times

The expected number of wins can be found by multiplying the probability of winning by the number of times played:

Expected number of wins = Probability of winning x Number of times played

Expected number of wins = 0.15 x 20

Expected number of wins = 3

Therefore, the answer is B. 3 times.

The probability of having a winning raffle ticket is 20%. If you bought 50 tickets, how many winning tickets should you expect to have?

A. 3 tickets
B. 8 tickets
C. 10 tickets
