Jane wants to buy a beautiful doll as a gift for her sister's birthday. She knows that the same product is offered in different shops with prices of $120, $100, and $80 with odds of one-third of finding each price.

Search once more and decide again upon knowing the price.
Accept the offer in hand.

Insufficient information to determine.
