1.   Jacob mixes the letters J, K, L, J, K, M, N, and P thoroughly. Without looking, Terry draws one letter. Expressed as a fraction, decimal, and percentage, what is the probability that K will not be the letter Terry selects

3/4 = 0.75 = 75%

First off, the user "Connexus"'s answer given is only partly correct.

You're welcome.

thanks

it was right

To find the probability that K will not be the letter Terry selects, we need to determine the number of favorable outcomes and the total number of possible outcomes.

Step 1: Determine the number of favorable outcomes.
In this case, the favorable outcomes are the letters other than K. So, the number of favorable outcomes is 7 (since there are 7 letters other than K).

Step 2: Determine the total number of possible outcomes.
The total number of possible outcomes is the total number of letters in the mixture, which is 8.

Step 3: Calculate the probability.
To calculate the probability, divide the number of favorable outcomes by the total number of possible outcomes.

Probability = Number of Favorable Outcomes / Total Number of Possible Outcomes

Probability = 7 / 8

Now let's express the probability as a fraction, decimal, and percentage:

Fraction: 7/8
Decimal: 0.875
Percentage: 87.5%

Therefore, the probability that K will not be the letter Terry selects is 7/8, 0.875, or 87.5%.
