A bag contains 6 blue marbles, 4 red marbles, and 2 yellow marbles. What is the probability of selecting a blue marble, replacing it, then selecting another blue marble?

Answers

Answer 1

Answer:

Probabilities are used to determine the chances of an event.

The probability of selecting 2 blue marbles (with replacement) is 1/4

The given parameters are:

$\mathbf{Blue = 6}\n\n$

$\mathbf{Red = 4}$

$\mathbf{Yellow = 2}$

The total number of marbles is:

$\mathbf{n =Blue + Red + Yellow }$

$\mathbf{n =6 + 4 + 2}$

$\mathbf{n =12}$

The probability of selecting 2 blue marbles (with replacement) is:

$\mathbf{Pr = (Blue)/(n) * (Blue)/(n)}$

$\mathbf{Pr = (6)/(12) * (6)/(12)}$

Simplify

$\mathbf{Pr = (1)/(2) * (1)/(2)}$

Multiply

$\mathbf{Pr = (1)/(4)}$

Hence, the probability of selecting 2 blue marbles (with replacement) is 1/4

0, 1, 4, 5, 6, and 9 can be the last digits of the squares of natural numbers.

Step-by-step explanation:

When looking at a list of the perfect squares, the last digits continuously follow this pattern: 1, 4, 9, 6, 5, 6, 9, 4, 1, 0. After this it repeats. This means that these are the only numbers that can be the last digits. When you take out the repeated numbers you get: 1, 4, 5, 6, 9, 0 which when written in order is:

0, 1, 4, 5, 6, and 9

16 times what equals 40

Answers

The complete statement is 16 times (5/2) equals 40.

What is a numerical expression?

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

let, 16 times 'x' equals to 40.

Therefore, 16x = 40.

x = 40/16.

x = 20/8.

x = 10/4.

x = 5/2.
