Probability is calculated by comparing the odds to a certain event occurring to the number of possible events.
P=
For example, take a six-sided dice number 1-6 on each side. The probability of rolling a 4 would be1 in 6 or 1/6. This is because of the six possible outcomes, rolling a 4 is only one of them.
P(4)=1/6
Now take the same dice. The probability of rolling an even number is 3/6. To see why, lets look at the total possible outcomes:
1
23
45
6
Of the 6 possibilities, 3 are even numbers.
P(even)=3/6 or 1/2
Answer:
70%
Step-by-step explanation:
49/70 = 0.7
0.7*100 = 70
Answer:
x=1
Step-by-step explanation:
(5x+−2x)+(3+−2)=4
3x+1=4
3x=3
x=1
12.56 because 12.56=2πr, so solve for r and you get 2=r. So you plug in 2 for r in the area formula which is A=πr^2, which will give you A=π(2^2), which is A=π(4), which will give you A=12.56
