Complete question :
You randomly choose a tile. Without replacing the first tile, you choose a second tile. Find the probability of the compound event. Write your answer as a fraction or percent rounded to the nearest tenth. The probability of choosing two even numbers is
Tiles : 7,6, 5, 8, 9, 10, 20
Answer:
2 /7
Explanation:
The probability of a compound event in the scenario described above :
P(1st pick) * p(second pick)
Recall: this event is without replacement
P(choosing two even numbers)
Probability = required outcome / Total possible outcomes
Required outcome = even Number tiles = (6, 8, 10, 20) = 4
Total possible outcomes = number of tiles = 7
P(even number on first pick) = 4/7
P(even on second pick) = 3 / 6 = 1/2
P(compound event) = 4/7 * 1 /2 = 4 /14 = 2 /7
