Chris has a bag with 4 black socks and 6 red socks (so there are 10 socks in total). Timothy reaches into the bag and grabs two socks without replacement. Find the
probability that he will not grab two red socks.

78/90

Step-by-step explanation:

p(BR)=6/10*4/9=24/90

p(RB)=4/10*6/9=24/90

p(BB)=6/10*5/9=30/90

add these together, you get 78/90

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
