Use the definition of o (f) to show that 4^n + 25 is o (5^n) (ii) show that 5^n is not o (4^n)

Step-by-step explanation:

i) if O (5^n)= 4^n + 25

O (f) should be = (20^n)/f + 25

Then

O(5^n)= (20^n)/(5^n) + 25 = (20/5)^n +25=4^n+25

ii) O (4^n)=(20^n)/(4^n) + 25 = (20/4)^n +25=5^n+25

And 5^n+25 is not = 5^n

blue marble is 15 times out of 50 = 15/50 reduces to 3/10

landing on tails is 24 out of 50 = 24/50 reduces to 12/25

to find the probability of both multiply together:

3/10 x 12/25 = 3 x 12 / 10 x 25 = 36/250

if you multiplied the numerator and denominator by 10 you get 360/2500.

the answer is 360/2500
