The main difference between BiPAP and CPAP machines is that BiPAP machines have two pressure settings: the prescribed pressure for inhalation (ipap), and a lower pressure for exhalation (epap). The dual settings allow the patient to get more air in and out of their lungs.
âSixes and sevensâ as we use it today actually has two related but distinct meanings. When we say âIâm all sixes and sevensâ or the like, it means that we are confused, disoriented and uncertain, either in general or in regard to a specific problem.ut âsixes and sevensâ can also mean a state of irreconcilable conflict, usually preceded by âatâ (âBob and Bill were best friends, but the arrival of Mary set them at sixes and sevens for the whole summerâ).
All the rolls are independent, so rolling double sixes twice in a row is the same as rolling a six (on one die) four times in a row. Since there are six choices, then each time there is a 1/6 chance of rolling a six.The fact they are entirely independent of each other means we simply multiply each roll's probability together: 1/6 Ã 1/6 Ã 1/6 Ã 1/6 = (1/6)4 = 1/1296 = 0.00077. Now let's say you had already rolled double sixes.ince there are six choices, then each time there is a 1/6 chance of rolling a six. The fact they are entirely independent of each other means we simply multiply each roll's probability together: 1/6 Ã 1/6 Ã 1/6 Ã 1/6 = (1/6)4 = 1/1296 = 0.00077.
