Hi

simple interest formual: I = prt

Questions states***

  $313.42 = p(.025)*3

Solving for p

  313.42/.075 = p

  $4178.93 = p



You roll a standard number cube. Find P(number greater than 1).

5 of the possible 6 outcomes arw >1 (2,3,4,5,6) 

  P(number greater than 1)= 5/6



French teacher will pick 3 students out of 26 at random.

26C3 = 26*25*24/2*3 = 2600 ways of picking 3    |nCx = n%21%2F%28x%21%28n-x%21%29%29

25C3 = 25*24*23/2*3 = 2300 ways of picking 3 (excluding Teesha)

P(Teesha will not be picked)= 2300/2600= .8846
