On a cube, you have 6 faces, therefore you have 1 chance to get 6 and 5 chances not to get 6.
Therefore, the overall probability not to get 6 is 5/6 = 0.8333
If you roll the cube 18 times, the prediction of unsuccessful rolls will be:
18 × 0.8333 = 15
Therefore, you expect to have 15 unsuccessful rolls over 18 total rolls.
Answer:
16 minutes
Step-by-step explanation:
If it takes 63 minutes to paint 9 walls then it means for every wall, it takes 63/9=7 minutes
Since it is 4 people working for 7 mins, the individual rate is 4/7 minutes per person
When we have 7 people, then the number minutes they take will be 7*4/7=4 minutes per wall
4 min per wall for 4 walls then total time will be 4*4=16 minutes

Answer:
£11,904
Step-by-step explanation:
Simple interest = PRT/100 where P = initial investment, R = rate and T = time.
So interest on £9600 = 9600*8*3/ 100
= £2304
So the value after 3 years = 9600 + 2304
= £11,904 (answer)
