A single die is rolled twice. Find the probability of rolling an odd

melisa1 [442]

Step-by-step explanation and answer:

The 6 sides of the die are numbered 1,2,3,4,5,6

There are 3 odd and 3 even numbers

probability of an odd number on 1st roll is:

3/6=1/2

When you want A AND B probabilities, you multiply

the events A and B

The number less than 3 are 1,2, so the probability is:

2/6=1/3

so the probability of both events are going to be:

(1/2) *(1/3)=1/6

What is 63.5% written as a decimal? A. 0.0635 B. 0.635 C. 6.35 D. 635

jek_recluse [69]

Answer:

B. 0.635

Step-by-step explanation:

Having a percent means its out of 100 so we can turn the percent into a fraction. 63.5/100

We cant have a decimal in our fraction, so we can multiply by 10 to get rid of it. (63.5*10)/(100*10)=635/1000

Since the denominator is a multiply of 10, we can convert the numerator into a decimal. .635

So your answer would be B. 0.635

All of the total number of spectators at a circus show 1/4 or men 2/5 of the remaining number of spectators are women there 132

kkurt [141]

Answer:

There are <u>198 children</u> at the circus show.

Step-by-step explanation:

Let the total number of spectators be 'x'.

Given:

Number of men = $\frac{1}{4}$ of the total number

Number of women = $\frac{2}{5}$ of the remaining number.

Also, number of women = 132

Number of men = $\frac{1}{4}\ of\ x=\frac{x}{4}$

Now, spectators remaining = Total number - Number of men

Spectators remaining = $x-\frac{x}{4}=\frac{4x-x}{4}=\frac{3x}{4}$

Now, number of women = $\frac{2}{5}\times \frac{3x}{4}=\frac{6x}{20}$

Now, as per question:

Number of women = 132. Therefore,

$\frac{6x}{20}=132$

$6x=132\times 20$

$x=\frac{2640}{6}=440$

Therefore, the total number of spectators = 440

Also, number of men = $\frac{x}{4}=\frac{440}{4}=110$

Now, total number of spectators is the sum of the number of men, women and children.

Let the number of children be 'c'.

Total number = Men + Women + Children

$440=110+132+c\\440=242+c\\c=440-242=198$

Therefore, there are 198 children at the circus show.
