The number of tickets purchased by an individual for Beckham College's holiday music festival is a uniformly distributed random variable ranging from 4 to 10.

The mean is 4.5 and the standard deviation is 1.44. Step-by-step explanation: An uniform probability is a case of probability in which each outcome is equally as likely. For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b. The mean of the uniform probability distribution is: The standard deviation of the uniform probability distribution is: Uniformly distributed random variable ranging from 2 to 7. This means that . So The mean is 4.5 and the standard deviation is 1.44.

the current is 0.6

voltage ÷ resistance = current

so 12 ÷ 20 = 0.6
