Given:
The probability for success of an event is P(A)
The probability of success of a second, independent event is P(B).
To find:
The probability of both events occurring, in that order.
Solution:
If A and B are two independent events, then

It is given that,
The probability for success of an event is P(A)
The probability of success of a second, independent event is P(B).
Since A and B both are independent event and we need to find the probability of both events occurring, in that order, i.e.,
, therefore
.
Hence, the correct option is A.
R - 10 = 18 - r
2r = 28
r = 14
The slope of line passing through the points (4, 4) and (10, 7) is 
<em><u>Solution:</u></em>
Given that, we have to find the slope of line that passes through the points (4, 4) and (10, 7)
The slope of line passing through
and
is given as:

Given two points are (4, 4) and (10, 7)

Substituting the values in formula, we get

Reducing to lowest terms, we get

Thus slope of line passing through given points is
