If the probability that an event occurs is 1/3, what is the probability that the event does not occur?

2/3

Step-by-step explanation:

The probability the event does not occur is 1 minus the probability the event does occur.

P = 1 − 1/3

P = 2/3

2/3.

Step-by-step explanation:

It either occurs or does not occur. There is no other result possible so the 2 probabilities add up to 1.

The answer is therefore 1 - 1/3 = 2/3.

26 is 33.33% of 78

step-by-step explanation:

26 is what percent of 78?

26 is p% of 78

equation: y = p% * x

solving our equation for p

p% = y/x

p% = 26/78

p = 0.3333

convert decimal to percent:

p% = 0.3333 * 100 = 33.33%
