Answer: 16 total starbursts.
Step-by-step explanation:
If 25% were pink, then 75% aren't pink. Let x be the total number of starbursts. We know that 75% of x = 12 (the ones that aren't pink). There is insufficient information to determine whether there is even one red starburst.
0.75x = 12
x = 12/(3/4)
x = 48/3
x = 16
There are 16 total starbursts:
25% are pink = 4 pink starbursts
75% aren't pink = 12 non pink starbursts
Total of 16 starbursts.
We can't answer how many were red. We aren't given any indication that there is even one red starburst. All we know is that 12 are not pink.
Answer:
a) 0.06
b) 0.3
c) 0.44
Step-by-step explanation:
We are given the following in the question:
A and B are two independent events.
P(A) = 0.3
P(B) = 0.2
a) P(A intersect B)
b) P(A|B)
c) P(A union B)
Answer: $28
to find 10% you need to divide by 10
10% = 3.5
20% = 7
35-7 = 28
C+p=15
5c+7p=91
multiply 5 to 1st equation and subtract it from 2nd
multiply 5 to 1st equation to get
5c+5p=75
now subtract this from 2nd equation
thats 2p=16
so
p=8
now we find c from
c+p=15
c=7
