Hospitals typically require backup generators to provide electricity in the event of a power outage. Assume that emergency backup generators fail 42% of the times when they are needed. A hospital has two backup generators so that power is available if one of them fails during a power outage. Complete parts (a) and (b) below.
Equations and Inequations
Equations and inequalities describe the relationship between two mathematical expressions.
Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.

Probability: The ratio of the number of favorable outcomes to certain event and total number of possible outcomes is called as the probability of an event.
Complementary events: If an event A is defined, then complement of event A is not occurring of event A.
Union of two events: The set of the outcomes that belong to either the two events or any of the two events is called as union of two events.
Intersection of two events: The set of the outcomes that belong to both the two events is called as intersection of two events.
Independent events: Two events A and B are said to be independent events if the occurrence of one event does not affect the occurrence of another event. In other words, if occurring of event A does not influence the event B occurring, then the two events A and B are independent.
The probability of an event is defined as,
