Step-by-step explanation:
Let
be a number.
When we multiply a number by 10:
(One '0' is increased in the number)
For example:

Considering a decimal number:

Multiplying a number with 0.1 (which is actually
) means dividing the number by 10.

Considering a decimal number:

<em>Therefore, When multiplying a number by 0.1, move the decimal to the left.</em>

Answer:
The answer is 0.123.
Step-by-step explanation:
You want to find the intersection between P(Spade) and P(Red). Knowing that there's no replacement, the probability will be given by the formula:
⇒ P(Spade∩Red) = P(Spade)*P(Red/Spade)
⇒ P(Spade∩Red) = P(Red)*P(Spade/Red)
Either formula works, but I'm going to choose to work with the first formula.
Therefore:
P(Spade) = 
P(Red/Spade) = 
So:
P(Spade∩Red) =
