Arectangular seating chart has an area of 10 in by 14 in. there are 2 in by 2 in squares with students’ names on it. what is the probability that a student is chosen to answer a question twice in a row? .
a.1/35
b.4/140
c.1/1225
d.2/1225

Probablity=desiredoutcomes/totalpossible

desired=1
total possible=number of squres

for 2 times in a row, we square the whole thing

10 by 14, so the area is 140

2 by 2 is 4
140/4=35 student squares

1/35 times 1/35 because selected twice
11225

C is answer
