Answer:

Last Option

P (B) = 0.6

Step-by-step explanation:

We have the Venn diagram that shows the probabilities of occurrence of 3 events A, B and C

In this case, since events A and B and B and C are non-disjoint events, then the probability of occurrence B is the sum of the probability that only B will occur plus the probability of occuring A and B plus the probability that B and C occur

This is:

P (B) = 0.1 +0.3 +0.2

P (B) = 0.6.

Solve 16(t - 1) + 10 > 8(t + 2) + 4(t - 1) + 4t.
Neporo4naja [7]

Answer:

The answer to your question is it has no solution

Step-by-step explanation:

Inequality

                   16(t - 1) + 10 > 8(t + 2) + 4(t - 1) + 4t

-Expand

                   16t - 16 + 10 > 8t + 16 + 4t - 4 + 4t

- Group like terms

                   16t - 8t - 4t - 4t > 16 - 4 + 16 - 10

-Simplify

                                       0 > 18

- It has no solution because the variable is cancelled.

The number 2.2360667… is a __ because it cannot be written as a fraction(ratio)
den301095 [7]

in our number " 2.2360667…" the 3 dots mean that the digits keep going forever,  so we conclude that our number belongs to the set of irrational numbers.

<h3>Which type of number is 2.2360667…?</h3>

We will define two types of numbers:

Rational numbers: Are these that can be written as the quotient of two integers.

Irrational numbers: Can't be written as the quotient of two integer numbers, A rational number always has an infinite number of digits after the decimal point, and there is no pattern in these digits.

Now, in our number " 2.2360667…" the 3 dots mean that the digits keep going forever, that is enough to conclude that our number belongs to the set of irrational numbers.

This probability distribution shows
Charra [1.4K]

Answer:

The probability that a student earns a grade of A is 1/7.

Let E be an event and S be the sample space. The probability of E, denoted by P(E) could be computed as:

P(E) = n(E) / n(S)

As the total number of students = n(S) = 35

Students getting the grade A = n(E) = 5

So, the probability that a student earns a grade of A:

                     P(E) = n(E) / n(S)

                             = 5/35

                             = 1/7

Hence, the probability that a student earns a grade of A is 1/7.

Keywords: probability, sample space, event
