A four-person committee is chosen from a group of eight boys and six girls. If students are chosen at random, what is the probab
Lapatulllka [165]

Answer: 0.07

Step-by-step explanation:

in the group, we can have only 4 persons.

we have 8 boys, and 6 girls.

We want to find the probability that in the comite we have only boys.

Ok, for the first selection, the probability of selecting a boy is equal to the number of boys divided the total number of the group ( 8 + 6 = 14) this is

p1 = 8/14.

For the second selection we do the same, but we already slected a boy, so now the number of boys is 7, and the total number of posibilities is 13.

p2 = 7/13.

for the third selection we do the same, in this case the probability is

p3 = 6/12

for the fourth selection the probability will be:

p4 = 5/11

The joint probability, of all the events happening at the same time, is equal to the product of the singular probabilities:

P = p1*p2*p3*p4 = (8/14)*(7/13)*(6/12)*(5/11) = 0.07

If each coded item in a catalog begins with 3 distinct letters followed by 4 distinct nonzero digits, find the probability of ran
laila [671]

Answer: 10/117

Step-by-step explanation:

3 distinct letters and 4 distinct nonzero digits

For letters: A → Z = 26 options

For numbers: 1 → 9 = 9 options

As we have 26 options for letters and 9 for numbers and they have to be distinct, for the total of codes we have

Total of codes: 26.25.24.9.8.7.6

For the particular code asked, we have 5 options of vowels and 4 options of even numbers, so

5.25.24.8.7.6.4

probability: <u>5.25.24.8.7.6.4</u> =    <u>10</u>

                   26.25.24.9.8.7.6     117

Which best describes the numbers satisfying the inequality x less-than 7?
vladimir1956 [14]

Answer:

x

Step-by-step explanation:

To find: inequality that describes the numbers x less-than 7

Solution:

An inequality compares two values a and b such that either one is less than i.e., a < b, greater than i.e., a > b, or simply not equal to another value i.e., a ≠ b. It describes a non-equal comparison two mathematical expressions.

Inequality that describes the numbers x less-than 7 is x
