Probability of at most two heads? Probability of at least one head? Assignment: p. 469-470 7.1 to 7.6. Continuous Random Variables. When we use the table of random numbers to select a digit between 0 and 9, the result is a discrete random variable. The probability model assigns probability 1/10 to each of the 10 possible outcomes (0 to 9).

A man and a woman have five children, all girls. Is it correct to assume that, if they have another child, probability would favor it being a boy? Explain. _____ A penny tossed 120 times results in 62 heads and 58 tails. In the space below, calculate the expected number of heads and tails and determine the percent deviation.

Calculating the chance of getting heads/tails is a bit tricky. Don't forget that . technically when you flip 2 coins and get a heads/tails that the heads could. be first or the tails could be first. You have to take this into consideration. when you find the probability of flipping heads/tails. Confusing? YOU BET!! First coin:
