Three coins are tossed and if one out of them is biased with heads on both sides then what is the probability of getting head on all the coins? Correct Answer 1/4

Given:

One out of three coins is biased with heads on both sides.

Concept used:

Probability = (probability of getting head on 1st coin) × (probability of getting head on 2nd coin) × (probability of getting head on 3rd coin)

Calculations:

Probability = (1/2) × (1/2) × (1)

⇒ 1/4

∴ The probability of getting head on all coins is (1/4).

Anika and Anushree always used to spend their time by playing coin games after their school hours. Once they decided to play a game of coins in which one player has to guess the number of coins by closing her eyes with the help of clues given by other player. During Anika’s turn, she closed Anushree’s eyes and put some coins on table. She then gave her clue by saying that one fourth of coins are showing their heads but if I turn over two coins then in that case, one third of them will show heads. So, Anushree can you guess how many number of coins I initially placed on the table?
Mrs. Richi Rich inherits 3224 gold coins and divides them amongst her 3 daughters Lalita, Palita and Salita in a certain ratio. Out of the total coins each of them received, Lalita sells her 50 coins, Palita donates 85 of her coins and Salita makes jewellery out of her 39 coins. Now the ratio of gold coins with them is 24 : 21 : 16 respectively. How many coins did Lalita receive from her mother ?
