Answer:
x = (14,15,16,,,,,,n)
Step-by-step explanation:
Here,x belongs to set of natural number N
and Condition given for set is " x is greater than 13 "
Now, N=(1,2,3,4,5,6,,,,n) and given that x > 13.
thus, x = (14,15,16,,,,,,n)
For every 7 hair bands there will be 4 ribbons
7 hair bands →→ 4 ribbons
14 hair bands →→ 8 ribbons
21 hair bands →→ 12 ribbons
etc.
P = 0.55 or 55 %
First step: Fred has probability of 0,5 when chossing jar 1 or jar 2
Second step : The probability of chossing one chocolate chp cookie in jar 1 is 3/5 and from the jar 2 is 1/2
Then the probability of Fred to get a chocolate chip cookie is
P ( get a chocolate chip cookie ) =( 0.5 * 3/5) +( 0.5* 1/2)
P = 0.3 + 0.25
