In a recent study on world happiness, participants were asked to evaluate their current lives on a scale from 0 to 10, where 0 represents the worst possible life and 10 represents the best possible life. The responses were normally distributed, with a mean of 6.3 and a standard deviation of 2.5. Answer parts (a)-(d) below. (a) Find the probability that a randomly selected study participant's response was less than 4. (Round to four decimal places as needed.) The probability that a randomly selected study participant's response was less than 4 is
