Answer:
65
Step-by-step explanation:
Hi,
I think you mean red or blue.
Number which are red or blue = 12 + 14
= 26% or 0.26
The number of red and blue = 0.26 * 250
= 65 marbles
Answer:
where is it?
Step-by-step explanation:
To solve these type of problems you need to use the pythagoras theorem ⇨ Hypotenuse² = Base² + Altitude².
Here,
- Altitude = 1.6 cm.
- Base = 1.2 cm
- Hypotenuse = x
Now, let's solve for x.
Hypotenuse² = Base² + Altitude²
x² = (1.2)² + (1.6)²
x² = 1.44 + 2.56
x² = 4
x = √4
x = <em><u>2</u></em><em><u>.</u></em>
- So, the value of x is <em><u>2</u><u> </u><u>cm.</u></em>

<u>NOTE</u><u> </u><u>:</u><u>-</u></h3>
- Pythagoras theorem can be used only in the cases of right-angled triangles. Here, it's given that the triangle is right angled so we can use this theorem.
- To solve the squares if decimals, take them as whole numbers & then just add the decimal points. For example, ⇨ for (1.2)², take it as 12² , then multiply 12 by 12, you'll get 144. Now, add the decimal place accordingly ⇨ 1.44 . So, (1.2)² = 1.44.
Answer:
1. The probability that B occurs or A does not occur (or both) is 0.73.
2. The probability that either B occurs without A occurring or A and B both occur is 0.73.
Step-by-step explanation:
It is given that the events A and B are mutually exclusive. It means the intersection of A and B is 0.
Given information:
We get,
(1) We need to find the probability that B occurs or A does not occur (or both).
Therefore the probability that B occurs or A does not occur (or both) is 0.73.
(2) We need to find the probability that either B occurs without A occurring or A and B both occur.
Therefore the probability that either B occurs without A occurring or A and B both occur is 0.73.
