Flipping a coin pt.4 (Mediocre....)
Probability
Level
2
I have two coins and two 10 sided dice. All are fair. I flip each coin once and roll each dice twice. What is the probability that I get two heads and four 10s (assuming it follows the laws of probability)? Give your answer in decimal form.
The answer is 0.000025.

Just find the product of all the probabilties that result in a win. Getting a head is 1/2 so doing it twice is 1/2*1/2=1/4. rolling a ten is 1\10 so doing it 4 times is (1/10)^4=1/10000. so the probabilty of both happening is 1/10000×1/4=1/40000=0.000025.
