You want to simulate rolling two six-sided dice. You are interested in how often you see a sum of 7 on the two dice.

Which of the following would simulate counting the number of times one would see a sum of 7 on two dice rolls when rolling the dice 25 times?

A
q ← 0
REPEAT 25 TIMES {
a ← RANDOM(1,6) + RANDOM(1,6)
IF (a = 7) {
q ← q +1
}
}
DISPLAY (q)

B
q ← 0
REPEAT 25 TIMES {
a ← RANDOM(1,6)
b ←  RANDOM(1,6)
IF (a = 7) {
q ← q + 1
}
}
DISPLAY (q)

C
q ← 0
REPEAT 25 TIMES {
a ← RANDOM(2,12)
IF (a = 7) {
q ← q +1
}
}
DISPLAY (q)

D
q ← 0
REPEAT 25 TIMES {
a ← 0
REPEAT 2 TIMES {
a ← a + RANDOM(1,6)
}
IF (a = 7) {
q ←  q + 1
}
}
DISPLAY (q)
