A six-sided die is rolled two times. What is the theoretical fractional probability that the first number is even and the second
Nostrana [21]

Answer:

The theoretical probability that the first number is even and the second number is odd is \frac{1}{4}.

Step-by-step explanation:

Since each dice has six sides, and there are two die, the total amount of different outcomes are 6^2 or 36. The probability of getting an even number on the first roll is \frac{3}{6} or \frac{1}{2}, and the probability of getting an odd number on the second roll is also \frac{3}{6} or \frac{1}{2}, so the probability of getting an even number on the first roll and an odd number on the second roll is \frac{1}{2} * \frac{1}{2} = \frac{1}{4}.

Suppose that you have an enormous grapefruit that is 92% water (by weight). The grapefruit weights 100 pounds. If the water cont
yuradex [85]

Answer:

The weight of grapefruit is now 80 pound.

Step-by-step explanation:

Consider the provided information.

Let the x is the weight loss. The weight of grapefruit is 100 pounds and water is 92%. After evaporation water is 90%.

Thus the weight loss is:

0.92\times100-0.90(100 - x) = x

92-90+0.90x=x

2=x-0.90x

2=0.1x

x=20

Hence, the weight loss is 80 pounds.

Therefore,  New weight is 100 - 20 = 80 pounds

The weight of grapefruit is now 80 pound.
