What is the least perfect square which is divisible by 24 30 and 60?
yanalaym [24]

Step 1: LCM of 24 , 30 and 60 = 120

so 120 is the least no which is divisible by all 24 , 30 and 60

Step 2: factors of 120 will be 2^3 * 3 * 5

so the least perfect square, which is divisible by 24, 30 and 60 will be
(2^3 * 3 * 5) x ( 2 * 3 * 5 ) = 3600

There are 23 countries in North America, 12 countries in South America, 47 countries in Europe, 44 countries in Asia, 54 countri
Eduardwww [97]

Using probability concepts, it is found that:

1. P(A) = 0.2268.

2. 100%.

3. 0%.

-------------------------

A probability is the <u>number of desired outcomes divided by the number of total outcomes.</u>

Item 1:

  • 44 countries in Asia.
  • Total of 23 + 12 + 47 + 44 + 54 + 14 = 194 countries.

Then:

P(A) = \frac{44}{194} = 0.2268

Itens 2 and 3:

  • The complement of an event is it's negation.
  • Either an event happens, or it does not, that is, either the event happens, or it's complement does, thus the sum of the probabilities of an event and it's complement is of 100%.
  • From the above bullet point, there is also a 0% probability that neither an event nor its complement happens.
