0.00
0.06
0.10
0.44
*0.50
4. Given that you roll a fair six-sided die, what is the probability that you roll an odd number? (1 point)

6. Which of the following represents the sample space for rolling a six-sided die and tossing a coin? (1 point)
{1H, 2H, 3H, 4H, 5H, 6H, 1T, 2T, 3T, 4T, 5T, 6T}
*{1, 2, 3, 4, 5, 6}
{H, T}
{1, 2, 3, 4, 5, 6, H, T}

3 answers

#3 ok
#4 There are 3 odd numbers out of 6. P(odd) = 1/2
#5 ok
#6 what happened to the coin? (A)
#7 ok
#8 ok

SO IS 6. {123456 H T}
