Jade used Fraction 3 over 4 yard of fabric to make a scarf. Can she make 2 of these scarves with Fraction 1 and 4 over 5 yards o

DochEvi [55]

Used 3/4 to make scarf

2 scarves needs 3/4+3/4=6/4=3/2 yard

can it be made with 1 and 4/5?
1 and 4/5=5/5+4/5=9/5
compare 3/2 and 9/5
times first fraction by 5/5 and 2nd by 2/2
15/10 and 18/10
15/10<18/10
yes, has enough
confused by the division, please use parenthasees like (3/4) instead of 'fraction 3 over 4'

C or D, very confused by words that are many

(c) what is the probability that at least one adult prefers milk chocolate to dark chocolate?

Schach [20]

Part A:

Given that 47% of adults prefer milk chocolate to dark chocolate, for a random sample of n = 4 adults, the probability that all four adults say that they prefer milk chocolate to dark chocolate is given by

$P(4)=(0.47)^4=0.049$

Part B:

The probability that exactly two of the four adults say they prefer milk chocolate to dark chocolate is given by

$P(2)={ ^4C_2(0.47)^2(1-0.47)^2} \\ \\ =6(0.2209)(0.2809)=0.372$

Part C:

The probability that at least one adult prefers milk chocolate to dark chocolate is given by

$P(at \ least \ 1)=P(X\geq1) \\ \\ =P(1)+P(2)+P(3)+P(4) \\ \\ =1-P(0)=1-{ ^4C_0(0.47)^0(1-0.47)^4} \\ \\ =1-(0.53)^4=1-0.0789=0.921$
