The probability of getting heads on a coin toss is
0.5
The probability of choosing a number <u>less</u> than four is
3/10 (1,2,3)
Therefore, the probability of getting heads <u>and</u> choosing a number less than four is:

Hope this helps!
3.5 - 3.2 = 3.8 - 3.5 = 4.1 - 3.8 = 0.3 (common difference)

Urgent care centers are often open all hours, but may not be as fully equipped (or staffed) to provide the sort of emergency medicine that a fully-equipped hospital can provide.
