James surveyed people at school and asked wether they bring their lunch to school or but their lunch at school more often. The results are shown below. The events male and buys lunch are not independent because

The correct answer is:

P(male | buys lunch) = 0.4 and P(male) = 0.3.

Explanation:

If two events A and B are independent, then P(A|B) {read "probability of A given B} is equal to P(A).

There are 176+46 = 222 males. There are 254+264 = 518 females. This is a total of 222+518 = 740 people. This makes P(male) = 222/740 = 111/370 = 3/10.

There are 176+264 = 440 people that buy lunch. Out of these, 176 are male. This makes P(male | buy lunch) = 176/440 = 88/220 = 8/20 = 4/10. This is because we consider only those who buy their lunch, and look at the probability that someone in that group is male.

Since P(male | buy lunch) = 4/10 ≠ P(male) = 3/10, these events are not independent.

answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.

step-by-step explanation: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.
