Step-by-step explanation:
because 9+14+10+7=40, you could say 9/40 or if you wanted to get a percent, you could multiply 40×2.5 ( because 40×2.5=100) then multiply 9×2.5 to get the percent
The probability of getting a redfish from this tank will be 35%.
Probability is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
Probability = Number of favorable outcomes / Number of sample
It is given that a tank at the pet store contains 9 spotted guppies 14 red barbs 10 res tetras and 7 golden platys.
The probability of getting a redfish from this tank will be calculated as:-
Number of samples = 9 + 14 + 10 + 7 = 40
Number of favorable outcomes = 14 red barbs
Probability = Number of favorable outcomes / Number of sample
Probability = 14 / 40
Probability = 0.35
Probability = 0.35 x 100 = 35%
Therefore, the probability of getting a redfish from this tank will be 35%.
