Answer 1

Question:

The number of parcel and the number of days of a courier company are given in the table below.observe the table and write the answer

number of parcels number of days

0-20 4

20-40 10

40-60 12

60-80 10

80-100 4

a) write the number of days on which least parcels arrived

b) If random number of days are selected then find the probability that the days selected will have parcels between 60-80.

c) find the mean number of parcels arrived

d) find the probability of getting highest number of parcels?

Answer:

a)  40 days

b)1÷5.

c)8

d)1÷5

Step-by-step explanation:

a) Least parcels 4 arrive for 0 to 20 and 80 to 100 days therefore a total of 40 days.

b)probability=Days selected÷Total number of days.

                      =20÷100=1÷5.

c) mean parcels= total parcels÷5

                        =8

d) probability of getting highest number of parcel= parcel in the range of 60 to 80÷total number of days.

      =20÷100

     =1÷5
