write an equation to represent the information in this problem. Jerel runs five days each week. on each of 4 days, he runs 2.3 km. if jerel runs a total of 14km, how many kilometers does he run on the fifth day?
Let x be the distance run on the fifth day
Total distance run on all the four days = 2.3 * 4 = 9.2 km
Required equation : x + 9.2 = 14
x = 14 - 9.2
x = 4.8 km

n(S)=55
Event E is the Event that the two numbers are odd.
Therefore: Complement of E will be the event that any of the two numbers is even.
The Sample Space of the complement of E is:
Therefore:
n(Eᶜ)=40
