Q.2 (A)

SCERT Maharashtra Question Bank solutions for 10th Standard SSC Mathematics 1 Algebra Maharashtra State Board Chapter 5 Probability Q.2 (A)

Complete the following activity [2 Marks]

Q.2 (A) | Q 1

If one die is rolled, then find the probability of the following event by completing the activity.

Event A: The number on the upper face is prime.

Activity: Let ‘S’ be the sample space.

S = {1, 2, 3, 4, 5, 6}  

∴ n(S) = 6

Event A: Prime number on the upper face.

A = {`square`}            

∴ n(A) = 3

P(A) = `square/(n(S))`    .....[Formula]

= `square/6`

∴ P(A) = `1/square`

Q.2 (A) | Q 2

Two coins are tossed simultaneously. Write the sample space (S) and expected sample points in the given events by completing the activity.

  1. Event A: to get at least one head.
  2. Event B: to get no head.

Activity: Let ‘S’ be the sample space, when two coins are tossed simultaneously.

∴ S = `{square, HT, TH, square}`

i. Event A: to get at least one head.

∴ A = `{HH, square, TH}`

ii. Event B: to get no head.

∴ B = `{square}`.

Q.2 (A) | Q 3

A card is drawn from a well shuffled pack of 52 playing cards. Find the probability of the event, the card drawn is a red card.

Activity: Let ‘S’ be the sample space.

∴ n(S) = 52

Event A: Card drawn is a red card.

∴ Total red cards = `square` hearts + 13 diamonds

∴ n(A) = `square`

∴ P(A) = `square/(n("S"))`    ......[Formula]

P(A) = `26/52`

P(A) = `square`

Q.2 (A) | Q 4

In Adarsh High School, out of 30 students in a class 3 students wear glasses (spectacles). If a student in the class is randomly selected, find the probability that he or she wears glasses (spectacles) by completing the following activity

Activity: There are a total of 30 students in the class.

∴ n(S) = `square`

Event: A selected student wears glasses (spectacles).

∴ n(A) = `square`

P(A) = `square/("n"("S"))`     ......[Formula]

P(A) = `square`

Event A: it is coffee chocolate.

Activity: Let ‘S’ be the sample space.

∴ n(S) = 5 + 6 + 2 = 13

Event A: it is a coffee chocolate.

∴ n(A) = `square`

∴ P(A) = `square/("n"("S"))`     .......[Formula]

P (A) = `square/13`
