The uniforms are numbered 0, 1, 2, ..., 99. That's 100 numbers. Half of them are odd and half of them are even. So the probability that any one of the uniforms is odd is 1/2 just like the probability that any one uniform is even is 1/2.

(a) The numbers on the uniforms are independent of one another. That is, the number of her cross-country uniform does not in any way determine the number on her basketball uniform and vice versa. This means that we can find the probability that each is odd and multiply these together using what is called the counting principle. The probability that all are odd is:
(1/2)(1/2)(1/2)=1/8

(b) This is done the same way we did part (a). Since the probability of any one uniform being odd is the same as it being even (1/2), the answer here is the same: (1/2)(1/2)(1/2)=1/8

(c) This problem differs from that in (a) and (b). There is only one way for all three uniforms to be odd numbers: (odd, odd, odd) or all even (even, even, even). However, there are multiple ways for the uniforms to be two odd and one even. If the uniforms are listed in order: cross-country, basketball, softball we can get exactly one even in any of three ways:
even, odd, odd
odd, even, odd
odd, odd, even
The probability for any one of these possibilities is (1/2)(1/2)(1/2)=1/8 but since there are three way the probability that we get even exactly once is equal to (3)(1/8) = 3/8

The density is 4, and the mass is 12.

So we just plug this into the equation

d = m/v

4 = 12/v

We know that the volume must be 3 to make the equation true, because 12/4 = 3.

Therefore, the answer is F. 3 cm ^3

A family ordered some candy bars and bags of chips for snacking. The number oof candy bars was twice as much as the number of ba
nikdorinn [45]

Answer:

The family bought 2 bags of chips

Step-by-step explanation:

Let the number of chips bags be  =   x

The number of candy bars  =  twice as much as the number of bags of chip

The number of candy bars  =  2x

The total cost  spent is  = $5.50

Therefore cost of all the chips bags + candy bars = 5.50

2x +  x = 5.50

3x = 5.50

x = \frac{5.50}{3}

x =  1.83

x = 2 (approx)

Thus the number of chips is 2 and the candy bars is 2(2) = 4 bags
