<span>the proccess of choosing is independent so probability of choosing from machin1 is:300/1000 =0.3
choosing from machin2 is:707/1010=0.7
the total result is 0.3*0.7=0.21 ;</span>
47. B 9
48, D 81
49. A 5
50 C 45
The asnwer is 28. Since 7 is one of the factors,and 7+x=11,you would do 11-7 to find x. After doing 11-7 to find x (4),then you multiply 7 and 4 since they are the factors of the missing number. 7×4 is 28,therefore,you are the number 28.
