Probability of sequences can be calculated by multiplying the chance of the first event by the chance of the second, and so on.
The probability of tossing a coin and getting heads is 50%, or 0.5, and the probability of selecting a number less than four from 1-10 is 40%, or 0.4.
The overall probability can then be expressed as:
0.5 x 0.4 = 0.2 or 20%
There is a twenty percent chance that a heads would be tossed and a number less than four selected.
1. 75% increase
2. 30% decrease
3. 80% increase
4. 25% decrease
Answer:
c = 2, d = 3
Step-by-step explanation:
multiply factors on left side gives
9 c 
= 18
( divide both sides by 9 )
c = 2
For both sides to be equal then
c = 2 and 3 + d = 6 ⇒ d = 3
As a check
left side = 2
× 9 = 18 = right side
Distance to checkpoint A from starting line = 20 yards.
Then from A to B distance = 12 yards.
Let us take starting point C.
So, it would make a right triangle.
We have AB = 12, AC = 20, we need to find BC, that is Hypotenuse of the right triangle.
According to Pythagoras theorem:
BC = 23.32.
<h3>Therefore, 23.32 yards is the distance from Checkpoint B to the starting line.</h3>
This would be a percent increase, so the formula would be:
New amount - Original amount / Original amount
Replace the numbers:
440 - 154 / 440
Simplify.
286 / 440
The chance would be 0.65, or 65%.
