A commuter must pass through five traffic lights on her way to work and will have to stop at each one that is red. She estimates the probability model for the number of red lights she hits, as shown below. $$\begin{array}{l|c|c|c|c|c|c}\chi=\# \text { of Red } & 0 & 1 & 2 & 3 & 4 & 5 \\\hline P(X=x) & 0.05 & 0.25 & 0.35 & 0.15 & 0.15 & 0.05\end{array}$$ a) How many red lights should she expect to hit each day? b) What's the standard deviation?
A commuter must pass through 5 traffic lights on her way to work and will have to stop at each one that is red. She estimates the probability model for the number of red lights she hits, as shown below. X=# of red 0 1 2 3 4 5 P(X=x) 0.04 0.25 0.36 0.14 0.15 0.06 (a) Compute the mean, or expected value, of the random variable X. (b) Compute the standard deviation of the random variable X.

A commuter must pass through 3 traffic lights on her way to work and will have to stop at each one that is red. She estimates the probability model for the number of red lights she hits, as shown below. Compute the mean, or expected value, of the random variable X. (Round to two decimal places as needed). X = number of red 0 1 2 3 P 0.2 ... 0.29 0.3
