- Two jars, A and B, hold 5 identical coins each, numbered from 0 to 9. Jar A contains even-numbered coins, while Jar B contains odd-numbered coins. One coin from each jars is randomly chosen simultaneously, without looking. The selected coins are combined to form a new number. i) The coin from Jar A represents the tens place and the coin from Jar B represents the ones place. Find the probability that the number formed is:
a) greater than 50. b) equal to 50.
ii) If the rule is changed such that the coin from Jar B represents the tens place and the coin from Jar A represents the ones place, does the probability of getting a number greater than 50 increase/decrease?
iii) The coins from the Jars are re-distributed
Answer the questions based on the given information. In the game of anthery, a bow ta The player stands far used to sho arrows at a target boant away from the board and aims the arrow so that it hits the board. One such board, which is divided into 4 concentric circular sections, is drawn on a coordinate grid as shown. Each section carries different points as shown in the igure. If an arrow lands on the boundary, the inner section points are awarded
(1)After shooting two arrows, Rohan scored 25 points. Write one set of coordinates for each arrow that landed on the target. [1]
(i) ti one player's arrow lands on (2.2.5), how many points will be awarded to the player? Show your work.
49
10 posts 30 points 130 polests
(ii) One of Rohan's arrow landed on (1.2, 1.6). He wants his second arrow to land on the line joining the origin a first arrow such that he gets 10 points for it. Find one possible pair of coordinates of the second arrow's landing mark
