If the probability of the event A is P(A) and the probability of the event B is P(B), then the probability P(A and B) is P(A)*P(B).

Since both P(A) and P(B) are equal to 1/2, then:

P(A\text{ and }B)=P(A)\cdot P(B)=\frac{1}{2}\cdot\frac{1}{2}=\frac{1}{4}

The sum of a number 1/6 of that number 2 1/2 of that number and seven is 12 1/2 find the number
Zigmanuir [339]

Answer:

Step-by-step explanation:

x = the number

x + 1/6x + 2 1/2x + 7 = 12 1/2

3 + (1/6 + 1/2)x = 12 1/2 - 7

3 + (1/6 + 3/6)x = 5 1/2

3 2/3x = 5 1/2

x = (11/2) / (11/3)

x = 11 / 2 * 3 / 11

x = 3/2

x = 1 1/2
