Answer:
- tttt, tttf, ttft, ttff, tftt, tftf, tfft, tfff fttt, fttf, ftft, ftff, fftt, fftf, ffft, ffff
- 840
- 84
- 504
Step-by-step explanation:
1. The sample space is all 16 possible sequences of T or F of length 4:
tttt, tttf, ttft, ttff, tftt, tftf, tfft, tfff fttt, fttf, ftft, ftff, fftt, fftf, ffft, ffff
__
2. The number of possibilities is the product of the numbers of choices at each stage:
5 × 7 × 4 × 6 = 840 . . . different meals
__
3. 9C3 = 9!/(3!·6!) = 84
__
4. 9P3 = 9!/6! = 504
Answer:
300, 120, 80 and 32 respectively.
Step-by-step explanation:
To break it down for easy multiplication, write
38 as 30 + 8
14 as 10 + 4
Now let's multiply
(30 + 8)(10 + 4) = 300 + 120 + 80 + 32
So the areas of each part would be
300, 120, 80 and 32 respectively.
