Jake trips over his dog 40% percent of mornings. 25% of the time he trips, he drops his coffee. What percentage of mornings does he NOT drop his coffee?
Ҷейк дар 40% субҳҳо ба саги худ хӯрда меравад. 25% вақт, вақте ки ӯ хӯрда меравад, қаҳваи худро меафканад. Кадом фоиз аз субҳҳо ӯ қаҳваи худро намеафканад?
How often does he trip? ** First multiply the chance of each event happening to find the chance they both happen: 40% * 25% = 10%
How often does he NOT drop his coffee? ** Then subtract that percentage from 100% to find the percentage of the time Jake doesn't drop his coffee: 100% - 10% = 90%
#### 90
