CUET-PG 2023 Shift 1 Question 98: Random variables and standard distributions

Suppose the distribution of weights of students in a college is normal with mean 60 kg and standard deviation 3 kg. Which of the following areas from the standard normal distribution gives the probability of a randomly selected student having weight less than 66 kg?

  1. Area to the left of z=−2z = -2z=−2
  2. Area to the left of z=2z = 2z=2
  3. Area to the right of z=2z = 2z=2
  4. Area to the right of z=−2z = -2z=−2
