$22($i$)$ The daily minimum temperature in degrees Celsius $(C)$ in January

in Ottawa is a random variable with distribution $N(-15\mathrm{.}1,62\mathrm{.}0).$ Find

the probability that a randomly chosen day in January in Ottawa has a

minimum temperature above $0C.$

$($ii$)$ In another city the daily minimum temperature in $C$ in January is a

random variable with distribution $N(,40\mathrm{.}0).$ In this city the probability

that a randomly chosen day in January has a minimum temperature

above $0C$ is $0\mathrm{.}8888.$ Find the value of $.$
