Answer:
The probability expressed as a fraction is: 1/5
The probability expressed as a decimal is: 0.2
The probability expressed as a percent is: 20%
Step-by-step explanation:
Probability is the likelihood or chance that am event will occur.
Probability = EXPECTED OUTCOME/TOTAL OUTCOME
If a bag contains 12 red, 14 blue, 10 green, 7 yellow, and 17 black marbles, the total number of marbles will be the TOTAL OUTCOME.
TOTAL OUTCOME = 12+14+10+7+17
TOTAL OUTCOME = 60
If the marble chosen at random is red, the total number of marbles will be our EXPECTED OUTCOME.
EXPECTED OUTCOME = 12
Probability of choosing red = 12/60
= 1/5 (as fraction)
Probability expressed as decimal = 0.2
Probability expressed as percent will be 1/5×100% = 20%
