Answer:
120 ways
Step-by-step explanation:
On the first day, John was 5 choices 5
On the second day he has 4 choices 4
On the third day he has 3 choices
On the fourth day he has 2 choices
On the fifth day he has 1 choice
5*4*3*2*1 = 120 different ways
1/3x > -4
cross multiply
1>-4 × 3x
1>-12x
solve for x
x = -1/12
Answer:30
3/10x=90
Use reciprocal to multiple both sides
x=answer
Answer: 0.4127
The probability formula to find p(F/E):
p(F/E)= N(E n F) / N(E)
p(F/E)= 260 / 630
p(F/E) = 0.4127
