Hat is he probability of pick 1 green marble from a bag with 7 green and 8 blue marbles
disa [49]

Answer:

7/15

Step-by-step explanation:

<em>No. of green marbles in the bag= 7</em>

<em>No. of blue marbles in the bag= 8</em>

<em>Total no. of marbles in the bag= 7+8=15</em>

As we know that,

Probability( of a random event A)= \frac{Favourable\ no.\ of\ elementary\ events}{Total\ no.\ of\ elementary\ events}

Hence in this case,

Favourable np. of elementary events (green marbles)=7

Total no. of elementary events (Total no. of marbles in the bag)= 15

Hence, Probability of picking a green marble from the bag=\frac{7}{15}

true or false The typical measurement of hotel demand is the room night (RN). When we say that each room night is perishable , w
weqwewe [10]

Answer:

True

Step-by-step explanation:

Perishable is a term for a product that has limited time to sell. A product like meat, fruit, and most fresh food will have a shelf life and you have to sell the product before the shelf life expires. Some preservation techniques can help to extend food products like freezing or curing them.

Room night of a hotel or any rent product is also considered as perishable since you can't store the rent time and sell it another day. So, every unoccupied room is treated as expired food. Unlike food products, room nights for the hotel can't be preserved. There are other strategies to maximize the revenue of rent products such as overselling or selling promise/reservation.
