In a standard deck of 52 cards, what is the probability that the first three cards drawn without replacement will be of different suits? Express your answer to the nearest whole percent.

*Solution to yesterday’s problem:*

The number of bacterial cells in the population can be expressed as the number of original cells *x* times two for each hour that the population doubles. We can write this as

where *n* is the number of hours and *P* is the population size. In the problem, we are given 7 hours and 38,400 cells. Substituting these into the equation:

Simplifying the exponent,

Dividing,

We conclude that there were *300 cells* in the original sample.
