Question

for traveling different mode of transport usedby 1500 people are as follows cycle 250, scooter 400, car 270 , bus220, train 260, no mode of transport. used atleast one kind of mode of transport.

Answer 1

Given :  different mode of transport used

To Find : no mode of transport.

used one kind of mode of transport.

Solution:

CYCLE        250

SCOOTER   400

CAR             270

BUS             220

TRAIN          260

Sub Total     1400

Used one kind of mode of Transport = 1400

no mode of transport = 1500 - 1400 = 100

Answer 2

Step-by-step explanation:

SOLUTION

GIVEN

For travelling, different mode of transport used by 1500 peoples are as follows:

Mode of Transport :: No. of Peoples

Cycle : 250

Scooter : 400

Car : 270

Bus : 220

Train : 260

No mode of transport : 100

TO DETERMINE

The probability of number of people

(i) Used car and scooter only

(ii) Used only cycle

(iii) Used at least one kind of mode of transport

EVALUATION

Here it is given that For travelling, different mode of transport used by 1500 peoples

So total number of peoples = 1500

So total number of possible outcomes = 1500

(i) Let A be the event that people use car and scooter only

Then the total number of possible outcomes for the event A = 400 + 270 = 670

So the required probability

= \sf{P(A)}=P(A)

\displaystyle \sf{ = \frac{670}{1500} }=

1500

670

\displaystyle \sf{ = \frac{67}{150} }=

150

67

(ii) Let B be the event that people use cycle only

So the total number of possible outcomes for the event B = 250

So the required probability

= P(B)

\displaystyle \sf{ = \frac{250}{1500} }=

1500

250

\displaystyle \sf{ = \frac{1}{6} }=

6

1

(iii) Let D be the event that people use at least one kind of mode of transport

So the total number of possible outcomes for the event D = 1500 - 100 = 1400

So the required probability

= P(D)

\displaystyle \sf{ = \frac{1400}{1500} }=

1500

1400

\displaystyle \sf{ = \frac{14}{15} }=

15
