Answer:
0.75
Step-by-step explanation:
4.5/6 = 0.75
The total number of fish available in the tank is (18 + 22) = 40. The probability for 1 goldfish to be taken out would be 18/40. Now, after drawing the first fish, the probability to get another goldfish would be 17/39. And the probability to draw 2 goldfish would be the product of both probabilities. P = (18/40)(17/39) = 51/260 So,the answer is B.
5 3/4 + 3 1/6
Make the 3/4 and 1/6 have common denominators. The least common denominator is 12. Multiply 3/4 by 3 on both sides and 1/6 by 2 on both sides.
5 3/4 ⇒ 5 9/12
3 1/6 ⇒ 3 2/12
Now you can add them up.
5 9/12 + 3 2/12 = 8 11/12
The answer is 8 11/12.
