Of all the different permutations of the letters in the word STOP, if you choose one at random, what is the probability that it will start with the letter P? Reduce your answer. PLEASE HELP!!

1/4

Step-by-step explanation:the word STOP has 4 letters so your probability of getting "P" is 1 in 4

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.

17

step-by-step explanation:

51/3=17

thus 17 is your answer.
