Your science teacher sets up six flasks. two of the flasks contain water and four of the flasks contain hydrogen peroxide. a reaction occurs when you add yeast to hydrogen peroxide. you add yeast to two of the flasks. what is the probability that at least one reaction will occur?

Step-by-step explanation:

Given:  Total number of flasks = 6

Number of flasks contain water =2

Number of flasks contains hydrogen peroxide =4

Total outcomes :Combination of 2 flasks out of 6 :-

Favorable outcomes : Combination of 2 flasks with at least one with hydrogen peroxide:

Now, the probability that at least one reaction will occur =

[∵ ]

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.
