Answer:

\frac{1}{4}

Step-by-step explanation:

Number of blue marbles = 8

Total number of marbles = 16+8+7+1=32

probability\: of \:selecting\: a\: blue\; marble\\=\frac{Number\: of\:blue\: marbles}{Total\: number\: of\: marbles} \\\\=\frac{8}{32} \\\\=\frac{1}{4}

The world famous gambler from Philadelphia, Senor Rick, proposes the following game of chance. You roll a fair die. If you roll
Orlov [11]

Answer:

You lose $0.833 while Rick gains $0.833, and so Rick is not Loco

Step-by-step explanation:

There are six numbers on a dice. Thus, probability of rolling exactly one number = 1/6

Probability of rolling two is 2/6.

Rolling a 1 pays $25, and probability = 1/6

Rolling a 2 pays $5,and probability = 1/6

Rolling a 3 pays $0, and probability = 1/6

Rolling a 4 or 5 pays -$10, and probability = 2/6

Rolling a 6 pays -$15, and probability = 1/6

Thus,lets calculate the expected value;

EV = (25 × 1/6) + (5 × 1/6) + (0 × 1/6) + (-10 × 2/6) + (-15 × 1/6)

EV = - $0.833

This means you lose $0.833 while Rick gains $0.833, and so Rick is not Loco.

Jim started cleaning at :1009 AM and finished at :1132 AM.<br> How long did it take him?
Goryan [66]

Answer:

1 hour and 23 minutes

Step-by-step explanation:

11:32-10:09=1:23

Thinking through this logically, one hour after 10:09 is 11:09 and we know that it took him longer than this.

We can then subtract the minutes without having to worry about the base-60.  

32 minutes -9 minutes =23 minutes

We then add the 23 minutes to the 1 hour and determine that it took him 1:23 (one hour and twenty-three minutes).
