Ben and Tom each take a driving test. The probability that Ben and Tom will pass is
0.8 and 0.7, respectively.
Please help

21, i'm pretty sure it's right lol

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
