Statistics and Probability

• not be uniform because the probability of rolling each number is different

• be uniform because the probability of rolling each number is different

• not be uniform because the probability of rolling each number is the same

• be uniform because the probability of rolling each number is the same

• Yes, because the probability of rolling an odd number is 1/2, and the probability of rolling an even number is 1/2

• Yes, because the probability of rolling an odd number is 1/10, and the probability of rolling an even number is 1/10

• No, because the probability of rolling an odd number is greater than the probability of rolling an even number

• No, because the probability of rolling an even number is greater than the probability of rolling an odd number

Each of the 20 students in Mr. Anderson's class flipped a coin ten times and recorded how many times it came out heads.  Use this data to estimate the probability of observing 4, 5, or 6 heads in ten tosses of the coin.
