Since participants have an equal chance of receiving each type of coupon, we can assume that 1/3 of the participants will receive a coupon for sleigh rides. Therefore, we can find the expected number of participants who will receive a coupon for sleigh rides by multiplying the total number of participants by 1/3:
900 * 1/3 = 300
So the answer is b) 300.
