An unfair coin is made so that heads is seven times as likely to come up as tails when the coin is flipped. An experiment consists of flipping this coin just once

What weight (or probability) does the outcome 'heads' have?
What weight (or probability) does the outcome 'tails' have?

Enter your answers as whole numbers or fractions in lowest terms.

An experiment has sample space S={a,b,c,d,e}. Outcomes b,c,d,e are equally likely while the likelihood of outcome a is Wa=7/19

Consider events E={a,c,e} and F={b,d,e}.

What is Pr(E)?
What is Pr(F)?
What is Pr(E∪F)?

Slim and Roy are flipping a unfair coin, where the coin has the chance to land on heads 65% of the time. Every time that the coin lands on heads, Slim gets 500 dollars from Roy, and Roy gets 500 dollars from Slim if the coin lands on tails. If the game is played 100 times (coin is flipped 100 times), what is the probability that Slim's winnings are $20,000 more than Roy's, where 'x' is strictly greater than 20,000...

Consider two coins, one fair and one unfair. The probability of getting heads on a given flip of the unfair coin is 0.10. You are given one of these coins and will gather information about your coin by flipping it. Based on your flip results, you will infer which of the coins you were given. At the end of the question, which coin you were given will be revealed. When you flip your coin, your result is based on a...
