Deena has 4 pairs of of white socks , 3 pairs of black sock, 1 pair of red socks, and 2 pairs of navy socks in her drawer each pair of socks is folded together . if she pulls a pair of socks out of her drawer in the morning without looking what is the probability she will choose a pair of white socks

The probability she will choose a pair of white socks is

Given that,

Total number of outcomes

We have to find the probability she will choose a pair of white socks.

Number of favourable outcomes

the probability she will choose a pair of white socks is,

2/5

Step-by-step explanation:

Ok there are 4+3+1+2 pairs of socks in all... Aka 10 sock pairs in all.

There are 4 white pairs.  So the probability she selects a white pair is 4/10.

4/10 can be reduced to 2/5.

answer: c, the green line

step-by-step explanation:

there is no black line, eliminate b.

simple interest implies periodic payments, but the red line shows no payments, eliminate d.

simple interest has equal payments. if paid say every day, the graph is about a straight line (actually a stairstep).

the yellow line is not straight, eliminate a.

check: the green line is straight, answer is c.

simple interest with positive interest rate gives a straight line sloping up to the right. green line:

g(t) = $100 + ($200-$100) ÷ (20 years) × (t years)

= $100 + (4%/year) × ($100)(t years)

incidentally, the yellow line curving upward represents continuously compounded interest

y = $100 × 2^(t years / (14 assuming the yellow line hits $200 at 14 years. 2^0 is 1, so y(0) = $100; 2^(14/14) is 2, so y(14) = $200.
