Which of the following should be kept in mind when deciding between mac and windows computers?

a. apple computers can’t run windows software .

b. apple computers are generally more expensive.

c. windows computers are more stable

d. windows computers are generally more expensive.

Part (a) is relatively straight forward.there are 4 aces in a standard 52-card deck. so the probability that an ace is picked is just 4/52.part (b): note that there are 4 suits in a standard 52-card deck. so picking hearts will be 13/52 or 1/4.part (c): the probability condition or means we need to add the two probabilities because we do not want them simultaneously. so, we end up getting pr(ace) + pr(heart).from part (a), we found that picking an ace had a probability of 4/52, which is reduced down to 1/13.from part (b), we found that picking a heart had a probability of 1/4.so, the probability of an ace or a heart is 1/13 + 1/4 = 4/52 + 13/52 = 17/52.

The correct answer is:   6.99 billion (as 6.986 billion is rounded off (to nearest hundredth place)  to 6.99 billion)explanation: the given function is:   y = 6.2(1.01)^x (1)where x =    number of years after 2000it means that in 2012, the value of x would be 12 as the difference between 2012 and 2000 is 12 years.put x = 12 in equation (1): (1) => y =  6.2(1.01)^12 = 6.986 billion = 6.99 billion
