Answer:
The answer is below
Step-by-step explanation:
We have the following information:
Number of songs you like = 2
Total number of songs = 12
a) P(you like both of them) = 2/12 x 1/11 = 0.015
This is unusual because the probability of the event is less than 0.05
b) P(you like neither of them) = 10/12 x 9/11 = 0.68
c) P(you like exactly one of them) = 2 x 2/12 x 10/11 = 0.30
d) If a song can be replayed before all 12,
P(you like both of them) = 2/12 x 2/12 =0.027
This is unusual because the probability of the event is less than 0.05
P(you like neither of them) = 9/12 x 9/12 = 0.5625
P(you like exactly one of them) = 2 x 2/12 x 9/12 = 0.25
Answer:
0.65g
Step-by-step explanation:
Decay rate = 50%
Decay rate = 0.5
where Ao = initial amount at start, k = rate of decay or growth, t = time, e = euler's number and A = value at time 't'
Ao = 4.8
t = 88/44 = 4
k = 0.5
substitute these values in the equation
