a bag contains 6 red blocks, 4 red blocks, 2 yellow blocks. three blocks. are taken from the bag, at random, without replacement. whats the probability that the three blocks will not be the same colour

0.1090908

Step-by-step explanation:

Given :

R = red blocks

Y = yellow blocks

G = green. blocks

n(R) = 6 ; n(Y) = 2 ; n(G) = 4

Total blocks = 6 + 2 + 4 = 12

Probability that all blocks are of same color :

P(RRR) or P(YYY) or P(GGG)

P(RRR) = 6/12 * 5/11 * 4/10 = 0.0909090

P(YYY) = 2/12 * 1/11 * 0/10 = 0

P(GGG) = 4/12 * 3/11 * 2/10 = 0.0181818

Hence,

0.0909090 + 0 + 0.0181818

= 0.1090908

For every 8 cars there are 7 trucks

Therefore,

Cars:Truck=8:7

Answer is B)8:7

The solution is in the following image

The answer is in the image 

F=ma

where F=force

m=mass

a=acceleration

Here,

F=4300

a=3.3m/s2

m=F/a

    =4300/3.3

    =1303.03kg

The answer is in the image 

Here,

tip=18%of $32

tip=(18/100)*32

=0.18*32

=$5.76

Total payment=32+5.76=$37.76

Salesperson will make 6% of 1800

=(6/100)*1800

=108

Salesperson will make $108 in $1800 sales
