hello i need help with these questuions

q1:

In the probability distribution to the right, the random variable X represents the number of hits a baseball player obtained in a game over the course of a season. Complete parts (a) through (c) below. F'(x) i:| 0.1534 0.3344 0.2348 0.149?Ir 0.0335 0.0242 mhmM'OX (a) Compute the mean of the random variable X. px = hits (Type an integer or a decimal. Do not round.) [b] Compute the standard deviation of the random variable X. 6X = hits (Round to three decimal places as needed.) (1:) What is the probability that in a randomly selected game. the player got more than 1 hit? (Type an integer or a decimal. Do not round.) For a certain candy, 5% of the pieces are yellow, 5% are red, 5% are blue. 5% are green, and the rest are brown. a) If you pick a piece at random. what is the probability that it is brown? it is yellow or blue? it is not green? it is striped? b) Assume you have an infinite supply of these candy pieces from which to draw. If you pick three pieces in a row, what is the probability that they are all brown? a) The probability that it is brown is D. (Round to three decimal places as needed.) The probability that it is yellow or blue is D. {Round to three decimal places as needed.) The probability that it is not green is D. (Round to three decimal places as needed.) The probability that it is striped is El. (Round to three decimal places as needed.) b) The probability of picking three brown candies is D. (Round to three decimal places as needed.) A hotel claims that 95% of its customers are very satisfied with its service. Complete parts a through c below based on a random sample of five customers. Leave your answers as a decimal DO NOT convert to a percent. a. What is the probability that exactly four customers are very satisfied? (Round to four decimal places as needed.) b. What is the probability that more than four customers are very satisfied? (Round to four decimal places as needed.) c. What is the probability that less than three customers are very satisfied? (Round to four decimal places as needed.)
