Answer 1

Answer:

Explanation:

SOLUTION:

Given :  All the black face cards are removed from a pack of 52 cards .

King, queen ,and jack are called face cards.

2 black Kings, 2 black queen and 2 black jack are removed from the Deck of 52 playing cards.

So, remaining cards in deck = 52 - 6 = 46

Total number of outcomes = 46

(i) We know ,that there are 12 face cards.

6 black face cards are removed.

Remaining face cards = 12 - 6 = 6  

Let E1 = Event of getting a face card

Number of favourable outcomes to E1= 6

Required probability P(E1)= Number of favourable outcomes / total number of outcomes

P(E1) = 6/46 = 3/23

Hence, the Required probability of getting a face card , P(E1) = 13/46

ii) We know ,that there are 26 red cards in a deck.  

Let E2 = event of getting a red card  

Number of favourable outcomes to  E2 = 26

Probability P(E2) = Number of favourable outcomes / total number of outcomes

P(E2) = 26/46 = 13/23

Hence, the Required probability of getting a red card,  P(E2) = 13/23

(iii) We know, that there are 26 black cards in a Deck .6 black face cards are removed Remaining black cards are = 26 - 6 = 20

Let E3 = Event of getting a black card

Number of favourable outcomes to  E3 = 20

Required probability P(E3) = Number of favourable outcomes / total number of outcomes

P(E3) = 20/46 = 10/23

Hence, the Required probability of getting a black card,  P(E3) = 10/23 .

(iv) We know ,that there are (2 black + 2 red) 4 king cards in a deck. 2 black kings are removed.

Remaining king card left = 4 - 2 = 2

Let E4 = Event  of getting a king  card

Number of outcome favourable to E4 = 2

Probability (E4) = Number of favourable outcomes / Total number of outcomes

P(E4) = 2/46 = 1/23

Hence, the required probability of getting a king  card , P(E4) = 1/23.

Answer 2

Answer:

I think it is silk route. For trade between two countries sea routes are the one and only way . But now there are more efficient and easier ways such as   air and road transport and importing and exporting had become so easier.

Technologies are also developed and globalization had established so it is simpler than the past.
