You can solve many simple probability problems just by knowing two simple rules:

<span> The probability of any sample point can range from 0 to 1.<span> The sum of probabilities of all sample points in a sample space is equal to 1. </span></span>

The following sample problems show how to apply these rules to find (1) the probability of a sample point and (2) the probability of an event.

Help me please!!!!! I need help with angles
Salsk061 [2.6K]

Answer:

<CFE = 28

<RPQ = 53

Step-by-step explanation:

1)

<CFE + 152 = 180

<CFE = 180 - 152

<CFE = 28

2)

Complementary means the angles add up to 90 so:

<RPQ + 37 = 90

<RPQ = 90 - 37

<RPQ = 53
