Answer:

0.4%

Step-by-step explanation:

In this case, because the coins have been replaced, the final probability would be multiplying the same probability six times (or raising it to exponent 6.). In other words, the probability of a dime coming out.

This probability would be the amount of dimes divided by the total number of coins, as follows:

Total coins = 10 + 8 + 2 = 20 coins.

So the probability would be: 8/20 = 2/5

The final probability would then be:

(2/5) ^ 6 = 0.004

In other words, the probability of this event occurring 6 times in a row is 0.4%

Of his 94 compact discs, Raul plans to donate 17 to the thrift store. To the nearest tenth of a percent, what percent is this?
Masteriza [31]
For this case we can solve the problem by means of the following rule of three:
 94 --------> 100%
 17 --------> x
 Clearing x we have:
 x = (17/94) * (100)
 x = 18,08510638%
 To the nearest tenth of a percent:
 x = 18.1%
 Answer:
 
This is 18.1% of his compact discs.
