Question

7. A 6-sided die is rolled 3 times. Find the probability ofrolling at least two 6? a. 0.074 b. 0.995 0.004 C. d. 0,028 0.069

Please explain in detail, it's for practice!

Answer 1

Answer #1

total possibilities of Rolling three dice = 6*6*6= 216

Rolling three six = $216 6 6 6$

Rolling two sixes

Case 1 = $5 5 1 216 6 6 6$

Case 2= $5 5 1 216 6 6 6$

Case 3= $5 5 216 6 6 6$

Probability of getting atleast two sixes = 5 16 5 0.074 + 216 216 216 216 216

correct option is (a) 0.074

A fair 6-sided die is rolled and you note whether the number facing up is even or odd. If an even number is rolled then a fair coin is flipped three more times and the number of heads is noted. But if an odd number is rolled then the coin is flipped only twice more and the number of tails is noted. How many possible outcomes are there for this experiment? (a) 43 (b) 20 (c) 7 (d) 45 (e)...
