Let S be a sample space of equally likely outcomes, and let event E be a subset of S. Then the probability that event E occurs is given by the formula P(E) = Start Fraction n (Upper E ) Over n (Upper S ) End Fraction . If the order of selection matters, use permutations to compute the number of ways for E to happen and to compute the size of the sample space. If it does not, use combinations.

Dakota earned $7.50 in interest in account a and $18.75 in interest in account b after 15 months. if the simple interest rate is 4% for account a and 5% for account b, which account has the greater principal? explain. to make it a little easier, there is an image. good luck!

How is working backward similar to solving an equation?

Me max recorded the heights of 500 male humans. he found that the heights were normally distributed around a mean of 177 centimeters. which statements about max’s data must be true? a) the median of max’s data is 250 b) more than half of the data points max recorded were 177 centimeters. c) a data point chosen at random is as likely to be above the mean as it is to be below the mean. d) every height within three standard deviations of the mean is equally likely to be chosen if a data point is selected at random.
